Gerald Sangudi updated PHOENIX-4917:
------------------------------------
Description:
This bug was introduced in the fix for PHOENIX-4791.
When projecting array elements in hash join, we now generate both
ProjectedTupleValue and MultiKeyTupleValue. Previously, we were only generating
ProjectedTupleValue, and there are two lines of code that contain this
assumption in class casts. The fix is to merge into the MultiKeyTupleValue,
while propagating the array cell as in PHOENIX-4791.
The stack trace with the ClassCastException:
