Review comment:
Thanks @kgyrtkirk .
This seems to need further exploration, we thought
https://issues.apache.org/jira/browse/HIVE-24087 was going to help here.
@vineetgarg02 , could you take a look at this once this patch is merged? Maybe
the shape of the plan is slightly different to the one we anticipated.
