    Description

      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.
