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.

Description

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
