Hemanth Yamijala updated HADOOP-2796:
-------------------------------------
Release Note: A provision to reliably detect a failing script's exit code
was added. In case the hod script option returned a non-zero exit code, users
can now look for a 'script.exitcode' file written to the HOD cluster directory.
If this file is present, it means the script failed with the returned exit code.
Hadoop Flags: [Reviewed]
> For script option hod should exit with distinguishable exit codes for script
> code and hod exit code.

> For hod script option, the exit code should distinguishable between hod exit
> code and script exit code.
> e.g.
> If script command contains the streaming command at end and that fails due to
> input path not found, its value exit cod will 5 which overlaps with hod exit
> code 5 which means "job execution failure"
> It would hod throws some distinguishable exit codes
> e.g
> For above examples 64 +5 =69 and we should this to get exact exit code of hod
> script command user should subtract 64 from exit code
