             Summary: Add Option to Pass Seed for JobID Hash for StandaloneJobClusterEntrypoint
                 Key: FLINK-12752
                 URL: https://issues.apache.org/jira/browse/FLINK-12752
             Project: Flink
          Issue Type: Sub-task
            Reporter: Konstantin Knauf
            Assignee: Konstantin Knauf


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): 

* --jobId
* --jobId-seed
* (default)

On Kubernetes, this new command line argument would need to be set to a property which is stable over Pod Restarts but changes for different K8s Jobs or K8s Deployments.
