Subject Task Attempt Failed
Date Mon, 08 Oct 2012 12:28:01 GMT
I'm starting to see the following error show up, but I don't know what it is trying to tell
me.  Does anyone know what this error means?

12/10/08 03:13:12 INFO mapred.JobClient: Task Id : attempt_201209281640_6895_m_007292_0, Status
java.lang.Throwable: Child Error
                at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:242)
Caused by: java.io.IOException: Task process exit with nonzero status of 126.
                at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:229)

The task is able to complete on the next attempt, so the job does not fail.  But, the job
takes a couple of hours when I don't see this message, longer when I do.  And I need to get
this job to complete faster if possible.

I'm running CDH3U3.  Any help would be greatly appreciated.
