Ashutosh Chauhan commented on HIVE-14241:
-----------------------------------------
I see. +1 for the patch. Lets do the follow-up of moving
FetchTask::initialize() in compileInternal() before execute() It doesn't seem
its any useful to do that in compile().
> Acid clashes with ConfVars.HIVEFETCHTASKCONVERSION <> "none"

> Some queries are optimized so as not to create an MR job. This somehow causes
> the Configuration object in FetchOperator to be passed to the operator before
> Driver.recordValidTxns() is called. So then to this op it looks like there
> are no valid txns and it returns nothing.
