Ashutosh Chauhan updated PIG-773:
---------------------------------
Attachment: pig-773_v3.patch
It turned out that there was a bug in DataType.java where schema for a Bag is
computed. The patch fixes the bug. Test cases are modified
to match the expected behavior. Also the values generated by the parser are
checked against expected values for the parsed constants.
> Empty complex constants (empty bag, empty tuple and empty map) should be
> supported
