The TestUlimit test is as follows :
The testcse sets the upper limit for virtual memory to 768 MB in the jobconf
Start a maponly job.
Let the task get the applicable ulimit from the shell and write it as the output.
The testcase will wait for the completion of the job and compare the joboutput with the ulimit originally set in the jobconf
But this testcase fails because all the task attempts fail with the following exception
java.lang.Throwable: Child Error
Caused by: java.io.IOException: Task process exit with nonzero status of 134.
So there is no job output .
The Test passes on my developer machine, but fails on the build machine which is a VM. The build machine OS is Red Hat Enterprise Linux Server release 6.1 (Santiago)
