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

             Summary: Pass RowTypeInfo to CodeGenerator instead of CRowTypeInfo
                 Key: FLINK-6486
                 URL: https://issues.apache.org/jira/browse/FLINK-6486
             Project: Flink
          Issue Type: Bug
            Reporter: Hequn Cheng
            Assignee: Hequn Cheng


For now CodeGenerator only process Row type, so we should pass RowTypeInfo to CodeGenerator instead of CRowTypeInfo. We can find these bugs in DataStreamGroupAggregate, DataStreamGroupWindowAggregate and DataStreamOverAggregate. These bugs will bring no error to the current flink because no code will make use of the error input type, however we should correct it.
