RE: Exit code 126?
We see this quite a bit.  There is a JIRA (I don't remember the number) that addresses this issue.  It has been applied to the apache distro, but I don't think it is incorporated in and release of CDH yet.

Subject: Exit code 126?


I ran a very simple rowcount (HBase) MR today, and one of the tasks failed with the status 126. Seems that there is no logs at all on the server side. Any idea what this mean?
