--------------------------------------------------------------------------
Key: MAPREDUCE-4128
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4128
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 3.0.0
Reporter: Bikas Saha
Assignee: Bikas Saha
Fix For: 3.0.0
The AM seems to assume that all attempts of a completed task (from a previous
AM incarnation) would also be completed. There is at least one case in which
this does not hold. Case being cancellation of a completed task resulting in a
new running attempt.
