Santhosh Srinivasan commented on PIG-571:
-----------------------------------------
As an intermediate step, Pig will parser the Hadoop status message and create
an exception with relevant details.
> pigserver methods do not throw error or return error code when an error occurs

> 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.
