PidFile issue
-------------

                 Key: CHUKWA-98
                 URL: https://issues.apache.org/jira/browse/CHUKWA-98
             Project: Hadoop Chukwa
          Issue Type: Bug
            Reporter: Jerome Boulon
            Priority: Blocker


Some processes like Collectors, demuxManager, etc have to be able to exit if they have to.
In that case, watchdog will not restart them since the shutdown hook will have done the cleanup.

    pFile = new PidFile("Agent");
    Runtime.getRuntime().addShutdownHook(pFile);

    pFile = new PidFile("Collector");
    Runtime.getRuntime().addShutdownHook(pFile);
