Do not assume if there is a local work, then there will be a map join operator in this work
-------------------------------------------------------------------------------------------

                 Key: HIVE-1732
                 URL: https://issues.apache.org/jira/browse/HIVE-1732
             Project: Hive
          Issue Type: Improvement
            Reporter: Liyin Tang
            Assignee: Liyin Tang


Right now, we simply assume if there is a local work, then there will be a map join operator.
This assumption is necessary true in the future.
Change the code of local work, either adding a type info or
creating sub class for each kind of local work, such as MapjoinLocalWork or GroupbyLocalWork.
