Till Rohrmann commented on FLINK-19005:
---------------------------------------
The per-job mode does also work in standalone mode via using
{{standalone-job.sh}}. But it won't stop the started {{TaskManagers}}. Hence it
is easier to use it when running on Yarn or K8s.
At the moment I think Chesnay's suggestion to put the dependency into {{/lib}}
is the best option to work around the problem. Once we have FLINK-17554, we
might also solve this problem in a more convenient way.

> Hi !
> Im running a 1.11.1 flink cluster, where I execute batch jobs made with
> DataSet API.
> I submit these jobs every day to calculate daily data.
> In every execution, cluster's used metaspace increase by 7MB and its never
> released.
> This ends up with an OutOfMemoryError caused by Metaspace every 15 days and i
> need to restart the cluster to clean the metaspace
> taskmanager.memory.jvm-metaspace.size is set to 512mb
> Any idea of what could be causing this metaspace grow and why is it not
> released ?
