Pig jobs - get stdout and stderr

[Jeff Yuan]

Is there an interface to get the standard out and standard error
streams for a pig execution? I'm using the Java interface and directly
calling PigServer.executeBatch() for example and getting back
List<ExecJob>. The ExecJob interface has some interface for getSTDOut
and getSTDError, but any calls to these result in
UnsupportedOperationException.

Thanks,
Jeff
