[jira] [Created] (TEZ-3394) Record the last reporting task for fetch failure diagnostics

Jason Lowe created TEZ-3394:
-------------------------------

             Summary: Record the last reporting task for fetch failure diagnostics
                 Key: TEZ-3394
                 URL: https://issues.apache.org/jira/browse/TEZ-3394
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Jason Lowe


It would be nice if the diagnostics for a fetch-failed task attempt also recorded the last task attempt that reported a fetch failure against it.  Then the user can quickly find one of the readers that encountered an error and check its logs for the nature of the fetch failure.

This is essentially the Tez equivalent of MAPREDUCE-6384.
