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

             Summary: Sort merge join should work if join cols are a prefix of sort columns for each partition
                 Key: HIVE-3774
                 URL: https://issues.apache.org/jira/browse/HIVE-3774
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Namit Jain
            Assignee: Namit Jain


Currently, a join is converted into a sort-merge join only if the join cols exactly matches the sort cols.
This constraint can definitely be relaxed.
