Thiruvel Thirumoolan commented on HIVE-2439:
--------------------------------------------
[~namit]
This is intended to simplify life for users of Hive, HCatalog and Pig. As
HCat/Pig use antlr 3.4, anyone using all the components have to workaround in
unfriendly and complicated ways. Thomas Weise raised this issue before
http://markmail.org/thread/xltnc5ak2saurdbu. Websearch for 'hive pig antlr'
also brings up workarounds like using jarjar.
While upgrading antlr, I also fixed problems in Hive.g that didn't surface with
3.0.1.
[~ashutoshc] Feel free to add if I have missed anything.
