             Summary: MapJoin with double keys is slow on MR
                 Key: HIVE-12354
                 URL: https://issues.apache.org/jira/browse/HIVE-12354

          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


Double keys are also a common type when comparing numbers with strings, and
