Igor Kryvenko commented on HIVE-12342:
--------------------------------------
[~djaiswal] I don't think that it changes product behavior. It wasn't done to
make tests pass it was done because it made unstably execution plan for the
{{TezCompiler}} . This change affects nothing except Tez. As far as I
understand it doesn't regress performance or anything else, anyway it looks odd
that we have the different plans for the same query.
Thanks, Igor.
