IMPALA-11280: Join node incorrectly picks up unnest(array) predicates
The expectation for predicates on unnested arrays is that they are
either picked up by the SCAN node or the UNNEST node for evaluation. If
there is only one array being unnested then the SCAN node, otherwise
the UNNEST node will be responsible for the evaluation. However, if
there is a JOIN node involved where the JOIN construction happens
before creatiing the UNNEST node then the JOIN node incorrectly picks
up the predicates for the unnested arrays as well. This patch is to fix
this behaviour.
Tests:
- Added an E2E test to cover result correctness.
- Added a planner test to verify that the desired node picks up the
predicates for unnested arrays.
