> Yarn single-job JobManagers should not allow uploads of new jobs.
> -----------------------------------------------------------------
>
> Key: FLINK-6455
> URL: https://issues.apache.org/jira/browse/FLINK-6455
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN, Runtime / Web Frontend
> Affects Versions: 1.2.1
> Reporter: Stephan Ewen
> Priority: Critical
>
> When running a job on Yarn in the 'single job cluster' mode, the web UI must
> not show the 'upload new job' option.
> If users actually submit another job via the web UI, the JobManager starts
> sharing the yarn cluster between these two jobs and there will be competition
> for TaskManagers between the jobs.
