Jin Xing updated CALCITE-3667:
------------------------------
Description:
Currently EnumerableMergeJoin use take-while enumerator [1] to emit values
satisfy predicate. However take-while enumerator stops the enumeration at once
when predicate is failed, which is not correct and we should finish the
enumeration and extract all the qualified values.
