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

             Summary: LLAP: Improvements to random selection while scheduling
                 Key: HIVE-15487
                 URL: https://issues.apache.org/jira/browse/HIVE-15487
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


Currently llap scheduler, picks up random host when no locality information is specified or
when all requested hosts are busy serving other requests with forced locality. In such cases,
we can pick up the next available node in consistent order to get better locality instead
of random selection.
