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

             Summary: PigToSqlAggregateRule should be applied on multi-set projection to produce
an optimal plan
                 Key: CALCITE-3297
                 URL: https://issues.apache.org/jira/browse/CALCITE-3297
             Project: Calcite
          Issue Type: Bug
          Components: piglet
            Reporter: Khai Tran


Fixed testMultisetProjection() in PigRelOpTest.java to make sure the PigToSqlAggregateRule
is applied to produce an optimized plan for doing multiset projection after COLLECT() agg
func.

The optimization rule was blocked by change in CALCITE-3138.
