>                 Key: FLINK-4487
>                 URL: https://issues.apache.org/jira/browse/FLINK-4487
>             Project: Flink
>          Issue Type: New Feature
>          Components: YARN
>    Affects Versions: 1.1.0
>            Reporter: Niels Basjes
>            Priority: Major
>
> There is a script yarn-session.sh which starts an empty JobManager on a Yarn cluster. 
> Desired improvements:
> # If there is already a yarn-session running then yarn-session does not start a new one (or it kills the old one?). Note that the file with ip/port may exist yet the corresponding JobManager may have been killed in an other way.
> # A script that effectively lets me stop a yarn session and cleanup the file that contains the ip/port of this yarn session and the .flink directory on HDFS.
