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

             Summary: LLAP: Executor memory and Xmx should have some headroom for other services
                 Key: HIVE-15347
                 URL: https://issues.apache.org/jira/browse/HIVE-15347
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran
            Priority: Critical


If executor memory + cache memory is configured close or equal to Xmx, the task attempts that
is causing OOM can take down the LLAP daemon. Provide some leeway for other services during
memory crunch.
