Siddharth Seth commented on PIG-4049:
-------------------------------------
[~rohini] - could you please open a Tez jira for the requested changes, and the
discussion can continue there for the Tez changes. I'm guessing you can
generally hit such cases whenever a limit operation is hit. +

would make use of events.
