> Projecting columns after {{LOAD}} via {{HBaseStorage}} produces unexpected results. This is related to the {{loadKey}} functionality and how the {{pushProjection}} method in {{HBaseStorage}} has to offset to build a column list that aligns with the tuple (the column list doesn't contain the row key).
> This shift appears to create an inconsistency with the FieldSchema for the tuple which results in the wrong tuple value being fetched for a given column. I'll attach a patch with unit tests that illustrate the problem.
