Stephan Ewen commented on FLINK-4487:
-------------------------------------
I think that the last changes for cluster management by [~mxm] will probably
address most of that.
> Need tools for managing the yarn-session better

> Key: FLINK-4487
> URL: https://issues.apache.org/jira/browse/FLINK-4487
> Project: Flink
> Issue Type: Improvement
> Components: YARN Client
> Affects Versions: 1.1.0
> Reporter: Niels Basjes
>
> 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.
