-----------------------------------
FAILURE: Integrated in Hadoop-Yarn-trunk #610 (See
[https://builds.apache.org/job/Hadoop-Yarn-trunk/610/])
MAPREDUCE-5956. Made MR AM not use maxAttempts to determine if the current
attempt is the last retry. Contributed by Wangda Tan. (zjshen:

> 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..
