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

             Summary: LLAP: reducers running in LLAP starve out map retries
                 Key: HIVE-10113
                 URL: https://issues.apache.org/jira/browse/HIVE-10113
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin
            Assignee: Gunther Hagleitner


When query 17 is run, some mappers from Map 1 currently fail (due to unwrap issue, and also
due to  HIVE-10112).
This query has 1000+ reducers; if they are ran in llap, they all queue up, and the query locks
up.
If only mappers run in LLAP, query completes.
