Koji Noguchi resolved PIG-5067.
-------------------------------
Resolution: Fixed
Fix Version/s: 0.17.0
Release Note:
This change now disallows union-onschema of incompatible types, (for example,
numeric types and chararray). It makes it consistent with plain union.
Thanks again for the review Daniel!
Committed to trunk.

> In PIG-2071, we changed the behavior of union on numeric and chararray to
> bytearray.
> This itself was always failing at runtime until we changed to skip the
> bytearray typecast for union-onschema in PIG-3270.
> (For union, it still fails with typecast to bytearray error. )
> Now, seeing users getting inconsistent results due to this union-ed bytearray.
