> TrackerDistributedCacheManager deletes the cached files when the size goes up to a configured number.
> But there is no such limit for the number of subdirectories. Therefore the number of subdirectories may grow large and exceed system limit.
> This will make TT cannot create directory when getLocalCache and fails the tasks.
