knaufk opened a new pull request #8741: [Flink 12752] Add Option to Pass Seed for JobID Hash for StandaloneJobClusterEntrypoint URL: https://github.com/apache/flink/pull/8741 ## What is the purpose of the change In case of a standalone job cluster setup, we would like to generate random a {{JobID}} for every job, but the {{JobID}} nevertheless needs to stay constant between JobManager process restarts. For this, I would like to add an additional command line options for the {{StandaloneJobClusterEntrypoint}} called {{jobId-seed}}. A manually specified jobId would still take precedence (not breaking current behavior): ## Brief change log * Use "--job-id-seed" in K8s Resource Definition templates (4 minutes ago) <Konstantin Knauf> * Adding job-id-seed parameter to StandaloneJobClusterEntrypoint (17 hours ago) <Konstantin Knauf> * [hotfix] unify spelling of "JobID" in flink-container module (17 hours ago) <Konstantin Knauf> ## Verifying this change * added tests in flink-container and flink-runtime module * build a flink job cluster image locally ``` ./build.sh --job-artifacts ../../flink-examples/flink-examples-streaming/target/flink-examples-streaming_2.11-1.9-SNAPSHOT-TopSpeedWindowing.jar --from-local-dist FLINK_JOB_ARGUMENTS="--job-id-seed this-is-a-special-seed FLINK_JOB=org.apache.flink.streaming.examples.windowing.TopSpeedWindowing docker-compose up ``` and verify that the generate Job ID is stable * follow instruction in flink-container/kubernetes/README.md to start a Job Cluster in Kubernetes with seed JobID This change added tests and can be verified as follows: ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented? flink-container/kubernetes/README.md
