Description

This is a follow-up issue to PHOENIX-539. There is currently an special case which disables the ChunkedResultIterator in the case of a hash join. This disabling of the ChunkedResultIterator is needed due to the fact that a hash join scan can return multiple rows with the same row key.

As discussed in the comments of PHOENIX-539, the ChunkedResultIterator should be updated to only end a chunk at between different row keys.
