Ashutosh Chauhan commented on HIVE-7111:
----------------------------------------
Also, I am not sure about usefulness of new test {{auto_join33.q}} Looking at
that test, I thought whats in it can already be achieved. So, I took that test
case and ran it on top of trunk and unsurprisingly it generated same plan. So,
this patch doesnt make a difference for that test. So, I am little unclear what
this patch is suppose to enable. It will be good to have a test case which
shows we have a better plan which wasn't possible without this patch.
> Extend join transitivity PPD to non-column expressions
