Rahul Palamuttam updated HIVE-8090:
-----------------------------------
Attachment: HIVE-8090.1.patch
A new boolean variable is introduced which checks if the codec is null or of
type ZlibCodec. This is substituted in place of the evaluated expression for
the boolean operator. Anymore conditionals for this to this parameter should be
updated to the new boolean variable.
