>
> Key: FLINK-8813

> Project: Flink
> Issue Type: Bug
> Components: JobManager, Tests
> Affects Versions: 1.5.0
> Reporter: Chesnay Schepler
> Assignee: Piotr Nowojski

> The {{AutoParallelismITCase}} fails when running against flip6.
> ([https://travis-ci.org/zentol/flink/jobs/347373854)]
> It appears that the {{JobMaster}} does not properly handle
> {{ExecutionConfig#PARALLELISM_AUTO_MAX}}.
>
> Exception:
> {code:java}
> Caused by: org.apache.flink.runtime.client.JobSubmissionException: Could not
> start JobManager.
