Prasanth Jayachandran commented on HIVE-18872:
----------------------------------------------
I don't understand the issue here. Could you please add description and
repro/testcase for this issue?
If the tablescan op changes the column list could also change. I am doubtful
about the code removal when iterating over "dirs" (which could be from
different table aliases).
