Hudson commented on MAPREDUCE-3125:
-----------------------------------

Integrated in Hadoop-Mapreduce-0.23-Build #46 (See [https://builds.apache.org/job/Hadoop-Mapreduce-0.23-Build/46/])
    MAPREDUCE-3125. Modified TaskImpl to consider only non-failed, non-killed task-attempts
for obtaining task's progress. Contributed by Hitesh Shah.

> ran same command as MAPREDUCE-3124. The app master web ui was displaying the reduce task
progress as 100% even though the states were still running/scheduled.  Each of those reduce
tasks had attempts that failed or killed and another one unassigned. Attaching screenshots.
