> As [~mbertozzi] comments on HBASE-16464,  there maybe race condition between 
> SnapshotManager and SnapshotCleaner.  We should use one lock when create 
> snapshot,  and cleanup should acquire the lock before take action.
> One method is pass HMaster as param into Cleaner through 
> {{FileCleanerDelegate.getDeletableFiles}},  suggestions are welcomed.
