Vikram Dixit K commented on HIVE-5129:
--------------------------------------
[~navis] This issue is related to HIVE-4692. I have attached a patch which
retains the same behavior as was before that patch without affecting the test
added as part of it. However, I am not sure what else is affected by this down
stream. I have started to run the unit tests to make sure I haven't broken
other things. It would be great if you could take a look and provide feedback
on this. Please let me know if you have a better approach in mind.
Thanks!
