Maryann Xue commented on PHOENIX-1580:
--------------------------------------

In Phoenix, RowProjector is only used as an adapter between ResultIterator and the jdbc Resultset.
The problem you have encountered is actually not caused by RowProjector, but by the aggregation
Expressions contained by the RowProjector. TupleProjectionPlan helps to push down these context-dependent
expressions into an internal layer from the interface layer (which is RowProjector here).
