[~mapohl] Hi Matthias,
I meet the same problem as [~gestevez] does. To figure out Metaspace leak is
not caused by my code, I specifically submit the word count job. And for every
times, the Metaspace grows up and never release. No matter how large the
Metaspace I configured, the Metaspace OOM will always occur.

> 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 ?
