--------------------------------------------------
Summary: MapReduce AM should not
Key: MAPREDUCE-5956
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5956
Project: Hadoop Map/Reduce
Issue Type: Sub-task
Reporter: Vinod Kumar Vavilapalli
Assignee: Vinod Kumar Vavilapalli
Priority: Blocker
Found this while reviewing YARN-2074. The problem is that after YARN-2074, we
don't count AM preemption towards AM failures on RM side, but MapReduce AM
itself checks the attempt id against the max-attempt count to determine if this
is the last attempt.
{code}
public void computeIsLastAMRetry() {
isLastAMRetry = appAttemptID.getAttemptId() >= maxAppAttempts;
}
{code}
This causes issues w.r.t deletion of staging directory etc..
