      Description

      I was running Flink 1.8 and decided to upgrade to 1.10. I started to get OutOfMemory: Metaspace on Task nodes and they would shutdown.

      Deploying 3-4 jobs was ok, deploying 5th job, the task manager would shutdown after a couple of minutes.

      Some investigation shows, that the Flink startup scripts set this to 100m.

      Setting taskmanager.memory.jvm-metaspace.size: 256m seems to alleviate the problem. Looking at the docs, this setting seems new. But it is not documented anywhere that the default is now 100m

      I would like to add the exact same setup/jobs on Flink 1.8 was working fine.

      Here is a conversation on the mailing list as well.

      I think the upgrade/migration docs should indicate this and also maybe the default size.
