                 Key: MAPREDUCE-2961
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2961
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Mahadev konar
            Assignee: Mahadev konar
             Fix For: 0.23.0


Currently the default threadpool size is 10 for launching containers in ContainerLauncherImpl. We should increase that to 100 for a reasonable default, so that container launching is not backed up by a small thread pool size.
