Zoltan Haindrich commented on HIVE-25278:
-----------------------------------------

this is essentally the same thing we already have in Calcite 
https://github.com/apache/calcite/blob/8430023f4616a9b239641b59420f56ecc3fa3e40/core/src/main/java/org/apache/calcite/rel/rules/ProjectJoinTransposeRule.java#L158
but we didn't had this in Hive
