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
