ShenDa commented on FLINK-19005:
--------------------------------
[~chesnay] I didn't do this on a local cluster. I use a script to submit job
for every 5 seconds on standalone cluster, so I don't know how many times
execution will trigger the OOM. it's a long time to occur by default Metaspace
configuration. But you can observe the usage of metatspace, you'll find that
the space never release and grows up continuously.
> used metaspace grow on every execution

> 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 ?
