URL: https://github.com/apache/hive/pull/687#issuecomment-506514522
@vineetgarg02 , I updated the PR. Note that ```hybridgrace_hashjoin_2.q```
issue will be tackled in HIVE-21928 so I think we can proceed with this issue.
In the latest patch I also added some simple logic to ```SharedWorkOptimizer```
to remove some duplicate filter expressions remaining in the plan because of
change in the shape of the expression (problem was existing, patch just exposed
it).
