Koji Noguchi commented on PIG-5235:
-----------------------------------
Another display issue I noticed while debugging, 'describe' now shows the types
BEFORE the typecast. For example, {{describe b}} using the script in
description would show
{noformat}b: {mytuple2: (name: bytearray,age: bytearray)}{noformat}
since as part of PIG-2315, I've reset the original user defined schema and let
the next typecast foreach take care of this. Trying to see if I can fix this
but may push to another jira.
