[jira] [Created] (TEZ-3462) Task attempt failure during container shutdown loses useful container diagnostics

Jason Lowe created TEZ-3462:
-------------------------------

             Summary: Task attempt failure during container shutdown loses useful container diagnostics
                 Key: TEZ-3462
                 URL: https://issues.apache.org/jira/browse/TEZ-3462
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.7.1
            Reporter: Jason Lowe


When a nodemanager kills a task attempt due to excessive memory usage it will send a SIGTERM followed by a SIGKILL.  It also sends a useful diagnostic message with the container completion event to the RM which will eventually make it to the AM on a subsequent heartbeat.

However if the JVM shutdown processing causes an error in the task (e.g.: filesystem being closed by shutdown hook) then the task attempt can report a failure before the useful NM diagnostic makes it to the AM.  The AM then records some other error as the task failure reason, and by the time the container completion status makes it to the AM it does not associate that error with the task attempt and the useful information is lost.
