-----------------------------------

             Summary: Reduce noisiness of SlotPool logging
                 Key: FLINK-9277
                 URL: https://issues.apache.org/jira/browse/FLINK-9277
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.5.0
            Reporter: Stephan Ewen
            Assignee: Till Rohrmann


The slot pool logs a vary large amount of stack traces with meaningless exceptions like {code}
org.apache.flink.util.FlinkException: Release multi task slot because all children have been released.
{code}

This makes log parsing very hard.

For an example, see this log: https://gist.githubusercontent.com/GJL/3b109db48734ff40103f47d04fc54bd3/raw/e3afc0ec3f452bad681e388016bcf799bba56f10/gistfile1.txt
