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).
