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.
