Ashutosh Chauhan commented on HIVE-1511:
----------------------------------------
First exception looks tractable.
Second one I have no idea. Only useful info w.r.t second one I have is if you
simulate this exact testcase (with same data and queries) on real cluster it
doesn't reproduce. Can't figure out why though?
