Ahmed Radwan commented on HADOOP-7752:
--------------------------------------

Mahadev, I faced this issue after I pulled the patch for HADOOP-7642, and t=
his is why I used it's same "affects versions". Based on Tucu's advice, I'l=
l pull also the latest changes from trunk including the MAPREDUCE-3003 patc=
h. I'll retest to make see if the problem persists.
