License. However, in accepting such obligations, You may act only

Commercial distributors of software may accept certain responsibilities

on Your own behalf and on Your sole responsibility, not on behalf

with respect to end users, business partners and the like. While this

license is intended to facilitate the commercial use of the Program,

of any other Contributor, and only if You agree to indemnify,

the Contributor who includes the Program in a commercial product

offering should do so in a manner which does not create potential

Contributor to the extent caused by the acts or omissions of such

Commercial Contributor in connection with its distribution of the Program

in a commercial product offering. The obligations in this section do not

|
apply to any claims or Losses relating to any actual or alleged

intellectual property infringement. In order to qualify, an Indemnified

writing of such claim, and b) allow the Commercial Contributor to control,

7. GENERAL
|
||||||
|
|
||||||
|
If any provision of this Agreement is invalid or unenforceable under
|
||||||
Unless required by applicable law or agreed to in writing, software
|
applicable law, it shall not affect the validity or enforceability of
|
||||||
|
the remainder of the terms of this Agreement, and without further

|
action by the parties hereto, such provision shall be reformed to the
|
||||||
|
minimum extent necessary to make such provision valid and enforceable.
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
|
|
||||||
|
If Recipient institutes patent litigation against any entity
|
||||||
See the License for the specific language governing permissions and
|
(including a cross-claim or counterclaim in a lawsuit) alleging that the
|
||||||
|
Program itself (excluding combinations of the Program with other software
|
||||||
limitations under the License.
|
or hardware) infringes such Recipient's patent(s), then such Recipient's
|
||||||
|
rights granted under Section 2(b) shall terminate as of the date such
|
||||||
|
litigation is filed.
|
||||||
|
|
||||||
|
All Recipient's rights under this Agreement shall terminate if it
|
||||||
|
fails to comply with any of the material terms or conditions of this
|
||||||
|
Agreement and does not cure such failure in a reasonable period of
|
||||||
|
time after becoming aware of such noncompliance. If all Recipient's
|
||||||
|
rights under this Agreement terminate, Recipient agrees to cease use
|
||||||
|
and distribution of the Program as soon as reasonably practicable.
|
||||||
|
However, Recipient's obligations under this Agreement and any licenses
|
||||||
|
granted by Recipient relating to the Program shall continue and survive.
|
||||||
|
|
||||||
|
Everyone is permitted to copy and distribute copies of this Agreement,
|
||||||
|
but in order to avoid inconsistency the Agreement is copyrighted and
|
||||||
|
may only be modified in the following manner. The Agreement Steward
|
||||||
|
reserves the right to publish new versions (including revisions) of
|
||||||
|
this Agreement from time to time. No one other than the Agreement
|
||||||
|
Steward has the right to modify this Agreement. The Eclipse Foundation
|
||||||
|
is the initial Agreement Steward. The Eclipse Foundation may assign the
|
||||||
|
responsibility to serve as the Agreement Steward to a suitable separate
|
||||||
|
entity. Each new version of the Agreement will be given a distinguishing
|
||||||
|
version number. The Program (including Contributions) may always be
|
||||||
|
Distributed subject to the version of the Agreement under which it was
|
||||||
|
received. In addition, after a new version of the Agreement is published,
|
||||||
|
Contributor may elect to Distribute the Program (including its
|
||||||
|
Contributions) under the new version.
|
||||||
|
|
||||||
|
Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
|
||||||
|
receives no rights or licenses to the intellectual property of any
|
||||||
|
Contributor under this Agreement, whether expressly, by implication,
|
||||||
|
estoppel or otherwise. All rights in the Program not expressly granted
|
||||||
|
under this Agreement are reserved. Nothing in this Agreement is intended
|
||||||
|
to be enforceable by any entity that is not a Contributor or Recipient.
|
||||||
|
No third-party beneficiary rights are created under this Agreement.

### 内部核心人员
|
### Generating test coverage reports ###
|
||||||
|
Generate coverage reports for the whole project:
|
||||||
`iceyuhui`、`liuyaguang`、`limengmonty`、`zhangliangmike`、`nullhuangyiming`、`zengqiao`、`eilenexuzhe`、`huangjiaweihjw`
|
|
||||||
|
./gradlew reportCoverage
|
||||||
|
|
||||||
### 外部贡献者
|
Generate coverage for a single module, i.e.:
|
||||||
|
|
||||||
`fangjunyu`、`zhoutaiyang`
|
./gradlew clients:reportCoverage
|
||||||
|
|
||||||
|
### Building a binary release gzipped tar ball ###
|
||||||
## 协议
|
./gradlew clean releaseTarGz
|
||||||
|
|
||||||
`kafka-manager`基于`Apache-2.0`协议进行分发和使用，更多信息参见[协议文件](./LICENSE)
|
The above command will fail if you haven't set up the signing key. To bypass signing the artifact, you can run:
|
||||||
|
|
||||||
|
./gradlew clean releaseTarGz -x signArchives
|
||||||
|
|
||||||
|
The release file can be found inside `./core/build/distributions/`.
|
||||||
|
|
||||||
|
### Cleaning the build ###
|
||||||
|
./gradlew clean
|
||||||
|
|
||||||
|
### Running a task with one of the Scala versions available (2.12.x or 2.13.x) ###
|
||||||
|
*Note that if building the jars with a version other than 2.12.x, you need to set the `SCALA_VERSION` variable or change it in `bin/kafka-run-class.sh` to run the quick start.*
|
||||||
|
|
||||||
|
You can pass either the major version (eg 2.12) or the full version (eg 2.12.7):
|
||||||
|
|
||||||
|
./gradlew -PscalaVersion=2.12 jar
|
||||||
|
./gradlew -PscalaVersion=2.12 test
|
||||||
|
./gradlew -PscalaVersion=2.12 releaseTarGz
|
||||||
|
|
||||||
|
### Running a task with all the scala versions enabled by default ###
|
||||||
|
|
||||||
|
Append `All` to the task name:
|
||||||
|
|
||||||
|
./gradlew testAll
|
||||||
|
./gradlew jarAll
|
||||||
|
./gradlew releaseTarGzAll
|
||||||
|
|
||||||
|
### Running a task for a specific project ###
|
||||||
|
This is for `core`, `examples` and `clients`
|
||||||
|
|
||||||
|
./gradlew core:jar
|
||||||
|
./gradlew core:test
|
||||||
|
|
||||||
|
### Listing all gradle tasks ###
|
||||||
|
./gradlew tasks
|
||||||
|
|
||||||
|
### Building IDE project ####
|
||||||
|
*Note that this is not strictly necessary (IntelliJ IDEA has good built-in support for Gradle projects, for example).*
|
||||||
|
|
||||||
|
./gradlew eclipse
|
||||||
|
./gradlew idea
|
||||||
|
|
||||||
|
The `eclipse` task has been configured to use `${project_dir}/build_eclipse` as Eclipse's build directory. Eclipse's default
|
||||||
|
build directory (`${project_dir}/bin`) clashes with Kafka's scripts directory and we don't use Gradle's build directory
|
||||||
|
to avoid known issues with this configuration.
|
||||||
|
|
||||||
|
### Publishing the jar for all version of Scala and for all projects to maven ###
|
||||||
|
./gradlew uploadArchivesAll
|
||||||
|
|
||||||
|
Please note for this to work you should create/update `${GRADLE_USER_HOME}/gradle.properties` (typically, `~/.gradle/gradle.properties`) and assign the following variables
|
||||||
|
|
||||||
|
mavenUrl=
|
||||||
|
mavenUsername=
|
||||||
|
mavenPassword=
|
||||||
|
signing.keyId=
|
||||||
|
signing.password=
|
||||||
|
signing.secretKeyRingFile=
|
||||||
|
|
||||||
|
### Publishing the streams quickstart archetype artifact to maven ###
|
||||||
|
For the Streams archetype project, one cannot use gradle to upload to maven; instead the `mvn deploy` command needs to be called at the quickstart folder:
|
||||||
|
|
||||||
|
cd streams/quickstart
|
||||||
|
mvn deploy
|
||||||
|
|
||||||
|
Please note for this to work you should create/update user maven settings (typically, `${USER_HOME}/.m2/settings.xml`) to assign the following variables
|
||||||
|
|
||||||
|
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
|
||||||
|
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||||
|
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
|
||||||
|
https://maven.apache.org/xsd/settings-1.0.0.xsd">
|
||||||
|

|
||||||
|
<servers>
|
||||||
|
...
|
||||||
|
<server>
|
||||||
|

|
||||||

|
||||||

|
||||||
|

|
||||||
|
<id>apache.releases.https</id>
|
||||||
|
<username>${maven_username}</username>
|
||||||
|
<password>${maven_password}</password>
|
||||||
|
</server>
|
||||||
|
...
|
||||||
|
</servers>
|
||||||
|
...
|
||||||
|
|
||||||
|
|
||||||
|
### Installing the jars to the local Maven repository ###
|
||||||
|
./gradlew installAll
|
||||||
|
|
||||||
|
### Building the test jar ###
|
||||||
|
./gradlew testJar
|
||||||
|
|
||||||
|
### Determining how transitive dependencies are added ###
|
||||||
|
./gradlew core:dependencies --configuration runtime
|
||||||
|
|
||||||
|
### Determining if any dependencies could be updated ###
|
||||||
|
./gradlew dependencyUpdates
|
||||||
|
|
||||||
|
### Running code quality checks ###
|
||||||
|
There are two code quality analysis tools that we regularly run, spotbugs and checkstyle.
|
||||||
|
|
||||||
|
#### Checkstyle ####
|
||||||
|
Checkstyle enforces a consistent coding style in Kafka.
|
||||||
|
You can run checkstyle using:
|
||||||
|
|
||||||
|
./gradlew checkstyleMain checkstyleTest
|
||||||
|
|
||||||
|
The checkstyle warnings will be found in `reports/checkstyle/reports/main.html` and `reports/checkstyle/reports/test.html` files in the
|
||||||
|
subproject build directories. They are also printed to the console. The build will fail if Checkstyle fails.
|
||||||
|
|
||||||
|
#### Spotbugs ####
|
||||||
|
Spotbugs uses static analysis to look for bugs in the code.
|
||||||
|
You can run spotbugs using:
|
||||||
|
|
||||||
|
./gradlew spotbugsMain spotbugsTest -x test
|
||||||
|
|
||||||
|
The spotbugs warnings will be found in `reports/spotbugs/main.html` and `reports/spotbugs/test.html` files in the subproject build
|
||||||
|
directories. Use -PxmlSpotBugsReport=true to generate an XML report instead of an HTML one.
|
||||||
|
|
||||||
|
### Common build options ###
|
||||||
|
|
||||||
|
The following options should be set with a `-P` switch, for example `./gradlew -PmaxParallelForks=1 test`.
|
||||||
|
|
||||||
|
* `commitId`: sets the build commit ID as .git/HEAD might not be correct if there are local commits added for build purposes.
|
||||||
|
* `mavenUrl`: sets the URL of the maven deployment repository (`file://path/to/repo` can be used to point to a local repository).
|
||||||
|
* `maxParallelForks`: limits the maximum number of processes for each task.
|
||||||
|
* `showStandardStreams`: shows standard out and standard error of the test JVM(s) on the console.
|
||||||
|
* `skipSigning`: skips signing of artifacts.
|
||||||
|
* `testLoggingEvents`: unit test events to be logged, separated by comma. For example `./gradlew -PtestLoggingEvents=started,passed,skipped,failed test`.
|
||||||
|
* `xmlSpotBugsReport`: enable XML reports for spotBugs. This also disables HTML reports as only one can be enabled at a time.
|
||||||
|
|
||||||
|
### Dependency Analysis ###
|
||||||
|
|
||||||
|
The gradle [dependency debugging documentation](https://docs.gradle.org/current/userguide/viewing_debugging_dependencies.html) mentions using the `dependencies` or `dependencyInsight` tasks to debug dependencies for the root project or individual subprojects.
|
||||||
|
|
||||||
|
Alternatively, use the `allDeps` or `allDepInsight` tasks for recursively iterating through all subprojects:
|
||||||
|
|
||||||
|
./gradlew allDeps
|
||||||
|
|
||||||
|
./gradlew allDepInsight --configuration runtime --dependency com.fasterxml.jackson.core:jackson-databind
|
||||||
|
|
||||||
|
These take the same arguments as the builtin variants.
|
||||||
|
|
||||||
|
### Running system tests ###
|
||||||
|
|
||||||
|
See [tests/README.md](tests/README.md).
|
||||||
|
|
||||||
|
### Running in Vagrant ###
|
||||||
|
|
||||||
|
See [vagrant/README.md](vagrant/README.md).
|
||||||
|
|
||||||

Trogdor
|
||||||
|
========================================
|
||||||
|
Trogdor is a test framework for Apache Kafka.
|
||||||
|
|
||||||
|
Trogdor can run benchmarks and other workloads. Trogdor can also inject faults in order to stress test the system.
|
||||||
|
|
||||||
|
Quickstart
|
||||||
|
=========================================================
|
||||||
|
First, we want to start a single-node Kafka cluster with a ZooKeeper and a broker.
|
||||||
|
|
||||||
|
Running ZooKeeper:
|
||||||
|
|
||||||
|
> ./bin/zookeeper-server-start.sh ./config/zookeeper.properties &> /tmp/zookeeper.log &
|
||||||
|
|
||||||
|
Running Kafka:
|
||||||
|
|
||||||
|
> ./bin/kafka-server-start.sh ./config/server.properties &> /tmp/kafka.log &
|
||||||
|
|
||||||
|
Then, we want to run a Trogdor Agent, plus a Trogdor Coordinator.
|
||||||
|
|
||||||
|
To run the Trogdor Agent:
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh agent -c ./config/trogdor.conf -n node0 &> /tmp/trogdor-agent.log &
|
||||||
|
|
||||||
|
To run the Trogdor Coordinator:
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh coordinator -c ./config/trogdor.conf -n node0 &> /tmp/trogdor-coordinator.log &
|
||||||
|
|
||||||
|
Let's confirm that all of the daemons are running:
|
||||||
|
|
||||||
|
> jps
|
||||||
|
116212 Coordinator
|
||||||
|
115188 QuorumPeerMain
|
||||||
|
116571 Jps
|
||||||
|
115420 Kafka
|
||||||
|
115694 Agent
|
||||||
|
|
||||||
|
Now, we can submit a test job to Trogdor.
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh client createTask -t localhost:8889 -i produce0 --spec ./tests/spec/simple_produce_bench.json
|
||||||
|
Sent CreateTaskRequest for task produce0.
|
||||||
|
|
||||||
|
We can run showTask to see what the task's status is:
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh client showTask -t localhost:8889 -i produce0
|
||||||
|
Task bar of type org.apache.kafka.trogdor.workload.ProduceBenchSpec is DONE. FINISHED at 2019-01-09T20:38:22.039-08:00 after 6s
|
||||||
|
|
||||||
|
To see the results, we use showTask with --show-status:
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh client showTask -t localhost:8889 -i produce0 --show-status
|
||||||
|
Task bar of type org.apache.kafka.trogdor.workload.ProduceBenchSpec is DONE. FINISHED at 2019-01-09T20:38:22.039-08:00 after 6s
|
||||||
|
Status: {
|
||||||
|
"totalSent" : 50000,
|
||||||
|
"averageLatencyMs" : 17.83388,
|
||||||
|
"p50LatencyMs" : 12,
|
||||||
|
"p95LatencyMs" : 75,
|
||||||
|
"p99LatencyMs" : 96,
|
||||||
|
"transactionsCommitted" : 0
|
||||||
|
}
|
||||||
|
|
||||||
|
Trogdor Architecture
|
||||||
|
========================================
|
||||||
|
Trogdor has a single coordinator process which manages multiple agent processes. Each agent process is responsible for a single cluster node.
|
||||||
|
|
||||||
|
The Trogdor coordinator manages tasks. A task is anything we might want to do on a cluster, such as running a benchmark, injecting a fault, or running a workload. In order to implement each task, the coordinator creates workers on one or more agent nodes.
|
||||||
|
|
||||||
|
The Trogdor agent process implements the tasks. For example, when running a workload, the agent process is the process which produces and consumes messages.
|
||||||
|
|
||||||
|
Both the coordinator and the agent expose a REST interface that accepts objects serialized via JSON. There is also a command-line program which makes it easy to send messages to either one without manually crafting the JSON message body.
|
||||||
|
|
||||||
|
All Trogdor RPCs are idempotent except the shutdown requests. Sending an idempotent RPC twice in a row has the same effect as sending the RPC once.
|
||||||
|
|
||||||
|
Tasks
|
||||||
|
========================================
|
||||||
|
Tasks are described by specifications containing:
|
||||||
|
|
||||||
|
* A "class" field describing the task type. This contains a full Java class name.
|
||||||
|
* A "startMs" field describing when the task should start. This is given in terms of milliseconds since the UNIX epoch.
|
||||||
|
* A "durationMs" field describing how long the task should last. This is given in terms of milliseconds.
|
||||||
|
* Other fields which are task-specific.
|
||||||
|
|
||||||
|
The task specification is usually written as JSON. For example, this task specification describes a network partition between nodes 1 and 2, and 3:
|
||||||
|
|
||||||
|
{
|
||||||
|
"class": "org.apache.kafka.trogdor.fault.NetworkPartitionFaultSpec",
|
||||||
|
"startMs": 1000,
|
||||||
|
"durationMs": 30000,
|
||||||
|
"partitions": [["node1", "node2"], ["node3"]]
|
||||||
|
}
|
||||||
|
|
||||||
|
This task runs a simple ProduceBench test on a cluster with one producer node, 5 topics, and 10,000 messages per second.
|
||||||
|
The keys are generated sequentially and the configured partitioner (DefaultPartitioner) is used.
|
||||||
|
|
||||||
|
{
|
||||||
|
"class": "org.apache.kafka.trogdor.workload.ProduceBenchSpec",
|
||||||
|
"durationMs": 10000000,
|
||||||
|
"producerNode": "node0",
|
||||||
|
"bootstrapServers": "localhost:9092",
|
||||||
|
"targetMessagesPerSec": 10000,
|
||||||
|
"maxMessages": 50000,
|
||||||
|
"activeTopics": {
|
||||||
|
"foo[1-3]": {
|
||||||
|
"numPartitions": 10,
|
||||||
|
"replicationFactor": 1
|
||||||
|
}
|
||||||
|
},
|
||||||
|
"inactiveTopics": {
|
||||||
|
"foo[4-5]": {
|
||||||
|
"numPartitions": 10,
|
||||||
|
"replicationFactor": 1
|
||||||
|
}
|
||||||
|
},
|
||||||
|
"keyGenerator": {
|
||||||
|
"type": "sequential",
|
||||||
|
"size": 8,
|
||||||
|
"offset": 1
|
||||||
|
},
|
||||||
|
"useConfiguredPartitioner": true
|
||||||
|
}
|
||||||
|
|
||||||
|
Tasks are submitted to the coordinator. Once the coordinator determines that it is time for the task to start, it creates workers on agent processes. The workers run until the task is done.
|
||||||
|
|
||||||
|
Task specifications are immutable; they do not change after the task has been created.
|
||||||
|
|
||||||
|
Tasks can be in several states:
|
||||||
|
* PENDING, when task is waiting to execute,
|
||||||
|
* RUNNING, when the task is running,
|
||||||
|
* STOPPING, when the task is in the process of stopping,
|
||||||
|
* DONE, when the task is done.
|
||||||
|
|
||||||
|
Tasks that are DONE also have an error field which will be set if the task failed.
|
||||||
|
|
||||||
|
Workloads
|
||||||
|
========================================
|
||||||
|
Trogdor can run several workloads. Workloads perform operations on the cluster and measure their performance. Workloads fail when the operations cannot be performed.
|
||||||
|
|
||||||
|
### ProduceBench
|
||||||
|
ProduceBench starts a Kafka producer on a single agent node, producing to several partitions. The workload measures the average produce latency, as well as the median, 95th percentile, and 99th percentile latency.
|
||||||
|
It can be configured to use a transactional producer which can commit transactions based on a set time interval or number of messages.
|
||||||
|
|
||||||
|
### RoundTripWorkload
|
||||||
|
RoundTripWorkload tests both production and consumption. The workload starts a Kafka producer and consumer on a single node. The consumer will read back the messages that were produced by the producer.
|
||||||
|
|
||||||
|
### ConsumeBench
|
||||||
|
ConsumeBench starts one or more Kafka consumers on a single agent node. Depending on the passed in configuration (see ConsumeBenchSpec), the consumers either subscribe to a set of topics (leveraging consumer group functionality and dynamic partition assignment) or manually assign partitions to themselves.
|
||||||
|
The workload measures the average produce latency, as well as the median, 95th percentile, and 99th percentile latency.
|
||||||
|
|
||||||
|
Faults
|
||||||
|
========================================
|
||||||
|
Trogdor can run several faults which deliberately break something in the cluster.
|
||||||
|
|
||||||
|
### ProcessStopFault
|
||||||
|
ProcessStopFault stops a process by sending it a SIGSTOP signal. When the fault ends, the process is resumed with SIGCONT.
|
||||||
|
|
||||||
|
### NetworkPartitionFault
|
||||||
|
NetworkPartitionFault sets up an artificial network partition between one or more sets of nodes. Currently, this is implemented using iptables. The iptables rules are set up on the outbound traffic from the affected nodes. Therefore, the affected nodes should still be reachable from outside the cluster.
|
||||||
|
|
||||||
|
External Processes
|
||||||
|
========================================
|
||||||
|
Trogdor supports running arbitrary commands in external processes. This is a generic way to run any configurable command in the Trogdor framework - be it a Python program, bash script, docker image, etc.
|
||||||
|
|
||||||
|
### ExternalCommandWorker
|
||||||
|
ExternalCommandWorker starts an external command defined by the ExternalCommandSpec. It essentially allows you to run any command on any Trogdor agent node.
|
||||||
|
The worker communicates with the external process via its stdin, stdout and stderr in a JSON protocol. It uses stdout for any actionable communication and only logs what it sees in stderr.
|
||||||
|
On startup the worker will first send a message describing the workload to the external process in this format:
|
||||||
|
```
|
||||||
|
{"id":<task ID string>, "workload":<configured workload JSON object>}
|
||||||
|
```
|
||||||
|
and will then listen for messages from the external process, again in a JSON format.
|
||||||
|
Said JSON can contain the following fields:
|
||||||
|
- status: If the object contains this field, the status of the worker will be set to the given value.
|
||||||
|
- error: If the object contains this field, the error of the worker will be set to the given value. Once an error occurs, the external process will be terminated.
|
||||||
|
- log: If the object contains this field, a log message will be issued with this text.
|
||||||
|
An example:
|
||||||
|
```json
|
||||||
|
{"log": "Finished successfully.", "status": {"p99ProduceLatency": "100ms", "messagesSent": 10000}}
|
||||||
|
```
|
||||||
|
|
||||||
|
Exec Mode
|
||||||
|
========================================
|
||||||
|
Sometimes, you just want to run a test quickly on a single node. In this case, you can use "exec mode." This mode allows you to run a single Trogdor Agent without a Coordinator.
|
||||||
|
|
||||||
|
When using exec mode, you must pass in a Task specification to use. The Agent will try to start this task.
|
||||||
|
|
||||||
|
For example:
|
||||||
|
|
||||||
|
> ./bin/trogdor.sh agent -n node0 -c ./config/trogdor.conf --exec ./tests/spec/simple_produce_bench.json
|
||||||
|
|
||||||
|
When using exec mode, the Agent will exit once the task is complete.
