Santhosh Srinivasan commented on PIG-571:

As an intermediate step, Pig will parser the Hadoop status message and create 
an exception with relevant details.

> I do PigServer.registerQuery("store ..."), and the query fails. Pig prints a 
> bunch of stack traces but does not throw an error back to the caller. This is 
> a major problem because my client needs to know whether the Pig command 
> succeeded or failed.
> I saw this problem with registerQuery() ... the same problem may arise with 
> other PigServer methods as well, such as store(), copy(), etc. -- not sure.
