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

             Summary: Improve error message when TaskManager fails
                 Key: FLINK-9276
                 URL: https://issues.apache.org/jira/browse/FLINK-9276
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.5.0
            Reporter: Stephan Ewen


When a TaskManager fails, we frequently get a message

{code}
org.apache.flink.util.FlinkException: Releasing TaskManager container_1524853016208_0001_01_000102
{code}

This message is misleading in that it sounds like an intended operation, when it really is a failure of a container that the {{ResourceManager}} reports to the {{JobManager}}.
