Rohini Palaniswamy updated PIG-4418:
------------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Committed to trunk and branch-0.15. Thanks for the review Daniel.
Note: The final patch committed will only help identify what is the root cause
of the issue and does not attempt to fix all the possible places of NPE. Since
the NPE is not expected to happen in the first place and is random and not
easily reproducible, it is better to identify the root cause in case the issue
has something to do with some garbage collection.
