Hudson commented on MAPREDUCE-2998:
-----------------------------------

Integrated in Hadoop-Hdfs-trunk-Commit #1002 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk-Commit/1002/])
    MAPREDUCE-2998. Fixed a bug in TaskAttemptImpl which caused it to fork bin/mapred too
many times. Contributed by Vinod K V.

> I am getting an exception frequently when running my jobs on a single-node cluster. 
It happens with basically any job I run: sometimes the job will work, but most of the time
I get this exception (in this case, I was running a simple wordcount from the examples jar
- where I got the exception 4 times in a row, and then the job worked the fifth time I submitted
it). 
> Sometimes restarting the namenode, resourcemanager, and historyserver helps - but not
always.  Several other developers have seen this problem.
