             Summary: Optimize FS internal data structures
                 Key: YARN-453
                 URL: https://issues.apache.org/jira/browse/YARN-453
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.0.3-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla

FS uses lists to store internal queues and sorts them on every heartbeat leading to unnecessary
scheduling overhead.

Choice of better data structures should reduce the latency.
