Hi all,

I have a weird failure occurring every now and then during a MapReduce job.

This is the error:

*java.lang.Throwable: Child Error*
* at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271)*
*Caused by: java.io.IOException: Task process exit with nonzero status of
255.*
* at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258)*
*
*
And sometimes it's the same but with *status of 126.*
*
*
Any ideas ?

Thanks.
