    Description

      We are seeing that when one of the localizerRunner stuck, the rest of the localizerRunners are blocked. We should remove the synchronized modifier.
      The synchronized modifier appears to have been added by https://issues.apache.org/jira/browse/MAPREDUCE-3537
      It could be removed if Localizer doesn't depend on current directory
