    Description

      For example, with https://github.com/apache/calcite/pull/1985, and enable top-down opt by set "calcite.planner.topdown.opt=true" in saffron.properties,

      run test case SortRemoveRuleTest.removeSortOverEnumerableHashJoin, we can see:

      java.lang.AssertionError
      	at org.apache.calcite.plan.volcano.OptimizeTask$RelNodeOptTask.execute(OptimizeTask.java:232)
      	at org.apache.calcite.plan.volcano.VolcanoPlanner.findBestExp(VolcanoPlanner.java:553)
      	at org.apache.calcite.tools.Programs$RuleSetProgram.run(Programs.java:327)
      	at org.apache.calcite.prepare.PlannerImpl.transform(PlannerImpl.java:362)
      	at org.apache.calcite.rel.rules.SortRemoveRuleTest.transform(SortRemoveRuleTest.java:77)
      	at org.apache.calcite.rel.rules.SortRemoveRuleTest.removeSortOverEnumerableHashJoin(SortRemoveRuleTest.java:102)
      

      The short term workaround is to comment the assert at OptimizeTask.java:232.
