Sergey Shelukhin updated HIVE-12294:
------------------------------------
Description: As far as I could tell, this should not happen because some
code in Hive iterates this list in parallel with names, assuming each ID will
correspond to a name; however, I've seen it in some logs recently. Either names
also contain duplicates and we should remove the line, or something could be
broken. Could also be different for different operators? No idea. (was: As
