> ClassCastException when projecting array elements in hash join

> Key: PHOENIX-4917
> URL: https://issues.apache.org/jira/browse/PHOENIX-4917
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.15.0, 4.14.1
> Reporter: Gerald Sangudi
> Assignee: Gerald Sangudi
> Priority: Major
> Fix For: 4.15.0, 4.14.1

> 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.
