             Summary: used metaspace grow on every execution
                 Key: FLINK-19005
                 URL: https://issues.apache.org/jira/browse/FLINK-19005
             Project: Flink
          Issue Type: Bug
          Components: API / DataSet, Client / Job Submission
    Affects Versions: 1.11.1
            Reporter: Guillermo Sánchez


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 ?
