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 : FAILED
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.
Thanks,
Dave Shine
