Peter Orova commented on OOZIE-3405:
------------------------------------
For the {{errorCode}} we could write the exit code of the submitted user script
into the {{.error}} file that is touched on failure. Any thoughts

> SSH action shows empty error Message and Error code

> Key: OOZIE-3405
> URL: https://issues.apache.org/jira/browse/OOZIE-3405
> Project: Oozie
> Issue Type: Improvement
> Reporter: Peter Orova
> Assignee: Peter Orova
> Priority: Minor
>
> Currently, when an SSH action fails the only message that is returned is the
> Status. Neither the {{error Message}} nor {{Error code}} fields are filled.
> This makes reporting on the causes of SSH Action failures via Oozie highly
> impractical: the only meaningful bit of information there is on a failed SSH
> Action is the Status.
> The Status is filled based on the presence (or lack of) the {{.error file}}
> that is produced in case the user submitted script returns with any other
> value than 0.
> {noformat}
> SshActionExecutor#getActionStatus
> ...
> String outFile = getRemoteFileName(context, action, "error", false, true);
> String checkErrorCmd = SSH_COMMAND_BASE + action.getTrackerUri() + " ls " +
> outFile;
> int retVal = getReturnValue(checkErrorCmd);
> ...
> {noformat}
>
> User requirement is to provide some more detailed information on the
> success/failure of the user-submitted script. That could be at a minimum the
> return value, optionally the last ~1K of the stderr that is drained. This
> information could then be communicated via {{errorMessage}} and {{ErrorCode}}
