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. Before the fix for PHOENIX-4791,
hash join was only generating ProjectedTupleValue, and there were two lines of
code with class casts that reflected this assumption. The fix is to handle both
ProjectedTupleValue and MultiKeyTupleValue, while continuing to propagate the
array cell as in PHOENIX-4791.
The stack trace with the ClassCastException:

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.
