Prasanth Jayachandran commented on HIVE-16503:
----------------------------------------------
test failures are unrelated to the patch. accumulo_index.q and accumulo_index.q
are already failing in master. skewjoinopt1.q passes locally for me which is
probably flaky. I will trigger another test run to make sure anyways.

> When running map joins in llap, it can potentially use more memory for hash
> table loading (assuming other executors in the daemons have some memory to
> spare). This map join conversion decision has to be made during compilation
> that can provide some more room for LLAP.
