[jira] [Created] (HIVE-9547) SortedDynPartitionOptimizer duplicates key columns in value

Ashutosh Chauhan created HIVE-9547:
--------------------------------------

             Summary: SortedDynPartitionOptimizer duplicates key columns in value
                 Key: HIVE-9547
                 URL: https://issues.apache.org/jira/browse/HIVE-9547
             Project: Hive
          Issue Type: Improvement
          Components: Logical Optimizer
    Affects Versions: 0.14.0, 0.13.0, 1.0.0, 1.1
            Reporter: Ashutosh Chauhan


SDPO used Extract Operator as a first operator in Reducer, so there was no way around it. After HIVE-9416 it has started to use Select Operator, so now its possible to do this change such that columns are not duplicated both in key and value.
