Subject [jira] [Created] (HIVE-12644) Support for offset in HiveSortMergeRule
Date Thu, 10 Dec 2015 12:31:10 GMT
Jesus Camacho Rodriguez created HIVE-12644:
----------------------------------------------

             Summary: Support for offset in HiveSortMergeRule
                 Key: HIVE-12644
                 URL: https://issues.apache.org/jira/browse/HIVE-12644
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


After HIVE-11531 goes in, HiveSortMergeRule needs to be extended to support offset properly
when it merges operators that contain Limit. Otherwise, limit pushdown through outer join
optimization (introduced in HIVE-11684) will not work properly.
