Eli Collins commented on MAPREDUCE-3709:
----------------------------------------

Diff'ing TestDistributedShell-output.txt from a successful run (on another 
host) and my machine does indicate the failure is due to the container getting 
killed due to running beyond its VM limits.

The test however still fails when making the following change to the pom.xml in 
hadoop-yarn-applications-distributedshell.

{noformat}
hadoop-trunk1 $ svn diff
