Jason Lowe created MAPREDUCE-4889:
-------------------------------------
Summary: AM should have a diagnostics message for invalid state
transitions
Key: MAPREDUCE-4889
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4889
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mr-am
Affects Versions: 0.23.5, 2.0.2-alpha
Reporter: Jason Lowe
When the ApplicationMaster encounters an invalid state transition in one of its
many state machines (JobImpl, TaskImpl, TaskAttemptImpl, etc.) the job will
fail with the ERROR state but the diagnostics string doesn't have any
information about the failure. The diagnostics string should contain a message
indicating the job is failing because of an invalid state transition and,
preferably, details on the nature of the internal error.
