Subject [jira] [Created] (MAPREDUCE-5754) Preserve Job diagnostics in history
Date Wed, 12 Feb 2014 04:47:19 GMT
Gera Shegalov created MAPREDUCE-5754:

             Summary: Preserve Job diagnostics in history
                 Key: MAPREDUCE-5754
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5754
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobhistoryserver, mr-am
            Reporter: Gera Shegalov
            Assignee: Gera Shegalov

History does not store the runtime diagnostics information. JobHistoryParser tries to blame
a task. We propose to preserve the original runtime diagnostics that covers all the cases
including the job being killed. This is particularly important in the context of user-supplied
diagnostic message as in MAPREDUCE-5648.
