> In ApplicationMaster, the priority of shutdown hook is set to 30, which expects higher than the priority of o.a.h.FileSystem.
> In FileSystem, the priority of shutdown hook is expressed as public constant named "SHUTDOWN_HOOK_PRIORITY" so I think it's better to use this constant for the priority of ApplicationMaster's shutdown hook.
