Mithun Radhakrishnan commented on HIVE-10720:
---------------------------------------------
Ok. Looks like I have held you up long enough. If you've verified that this
code path works without HIVE-5193, let's roll it back, and revisit this fix in
a separate JIRA. We will try identify how this works correctly on our internal
branch. Viral, does that sound ok?
Sorry for the delay. I applaud your diligence and patience, Aihua. Thank you. :]
