Maryann Xue resolved PHOENIX-3724.
----------------------------------
Resolution: Fixed
Assignee: Maryann Xue (was: Rajeshbabu Chintaguntla)
Thank you very much, [~rajeshbabu], for finding this issue! The problem was
that the new "extendedColumnRef" was not computed correctly and thus prevented
the exit condition of the rule from taking effect.
So the fix is to set the {{extendedColumnRef}} right before passing it into the
{{PhoenixTableScan}} constructor and then assert that it contains the columns
used by the filter within the constructor.
