Vineet Garg commented on HIVE-20811:
------------------------------------
[~sershe] I have retracted my description about correctness, I thought I saw an
issue where dynamic hash join produces wrong result but I probably confused it
with some other issue.
Anyhow I believe it should be turned on by default since customers have been
using it and by keeping it ON for all tests would help uncover issues (e.g.
HIVE-20514).
