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

             Summary: remove FlinkAggregateExpandDistinctAggregatesRule when we upgrade calcite
                 Key: FLINK-5545
                 URL: https://issues.apache.org/jira/browse/FLINK-5545
             Project: Flink
          Issue Type: Bug
            Reporter: Zhenghua Gao
            Assignee: Zhenghua Gao
            Priority: Minor


We copy calcite's AggregateExpandDistinctAggregatesRule to Flink project, and do a quick fix to avoid some bad case mentioned in CALCITE-1558.
Should drop it and use calcite's AggregateExpandDistinctAggregatesRule when we upgrade to calcite 1.12(above)
