Jesus Camacho Rodriguez updated CALCITE-996:
--------------------------------------------
Description: When we create a Filter operator, there is a chance we end up
with duplicate predicate factors (for instance, this has been seen in Hive when
we use FilterMergeRule). It seems appropriate to simplify the predicate to
eliminate those factors before we create the filter. (was: When we call
FilterMergeRule, there is a high probability that we end up with duplicate
predicate factors. It seems appropriate to simplify the predicate to eliminate
those factors before we create the merged filter.)
