    Description

      I ran a query with join and group by with below settings, COB failed due to NullPointerException in HiveAggregate.isBucketedInput()

      set hive.execution.engine=tez;

      set hive.cbo.costmodel.extended=true;

       

      In class HiveRelMdDistribution, we implemented below functions:

      public RelDistribution distribution(HiveAggregate aggregate, RelMetadataQuery mq)

      public RelDistribution distribution(HiveJoin join, RelMetadataQuery mq)

       

      But in HiveAggregate.isBucketedInput, the argument passed to distribution is "this.getInput()"

      , obviously it's not right here. The right argument needed is "this"
