[jira] [Created] (CALCITE-3755) Ascending rule match with RelSubset operand doesn't work

Haisheng Yuan created CALCITE-3755:
--------------------------------------

             Summary: Ascending rule match with RelSubset operand doesn't work
                 Key: CALCITE-3755
                 URL: https://issues.apache.org/jira/browse/CALCITE-3755
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Haisheng Yuan


Given a rule with match pattern {{operand(Filter, operand(RelSubset))}}, when we add a new RelSubset into the set, planner will fire rules for RelSubset. 
But in {{VolcanoRuleCall.matchRecurse}}, if !inputRels.contains(previous), it will skip. Obviously, the input rels will never contain a RelSubset, hence fails to match the rule.
