Contrib/Streaming - Test org.apache.hadoop.streaming.TestUlimit fails on VM
---------------------------------------------------------------------------

                 Key: MAPREDUCE-3594
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3594
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/streaming
    Affects Versions: 0.22.0
         Environment: Red Hat Enterprise Linux Server release 6.1 (Santiago)
            Reporter: Benoy Antony
            Priority: Minor



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 
        at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:225) 
Caused by: java.io.IOException: Task process exit with nonzero status of 134. 
        at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:212) 

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)
