-----------------------------------

             Summary: AggregateExpandDistinctAggregatesRule should work on Aggregate instead of LogicalAggregate
                 Key: CALCITE-1782
                 URL: https://issues.apache.org/jira/browse/CALCITE-1782
             Project: Calcite
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Haohui Mai


{{AggregateExpandDistinctAggregatesRule}} expects the operator to be a subclass of {{LogicalAggregate}}:

{noformat}
  public AggregateExpandDistinctAggregatesRule(
      Class<? extends LogicalAggregate> clazz,
      RelFactories.JoinFactory joinFactory) {
    this(clazz, false, RelBuilder.proto(Contexts.of(joinFactory)));
  }
{noformat}

However, {{LogicalAggregate}} is a final class which cannot be inherited. This jira proposes to change the signature from {{LogicalAggregate}} to {{Aggregate}}.
