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:
