      Description

      Currently, the FairScheduler configuration file fair-scheduler.xml is loaded only on ResourceManager startup.

      We need:

      • a mechanism to rescan / reload-if-changed this, often-changing piece of RM configuration
      • from classpath / configuration file:
        • configuration file wins over classpath
      • rescan every n seconds, where:
        • n <= 0 means don't rescan
        • n > 0 means rescan every n seconds
