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

             Summary: Tone down scary executor lost messages when killing on purpose
                 Key: SPARK-4134
                 URL: https://issues.apache.org/jira/browse/SPARK-4134
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.2.0
            Reporter: Andrew Or
            Assignee: Andrew Or


After SPARK-3822 goes in, we are now able to dynamically kill executors after an application
has started. However, when we do that we get a ton of scary error messages telling us that
we've done wrong somehow. It would be good to detect when this is the case and prevent these
messages from surfacing.

This maybe difficult, however, because the connection manager tends to be quite verbose in
unconditionally logging disconnection messages. This is a very nice-to-have for 1.2 but certainly
not a blocker.
