      Description

      There is no cleanup function in hbase.io.hfile.CacheConfig. The cache is a singleton, shared by all cluster if we launch more than one cluster on a test.

      Related code is:

        /**
         * Static reference to the block cache, or null if no caching should be used
         * at all.
         */
        private static BlockCache globalBlockCache;
      
        /** Boolean whether we have disabled the block cache entirely. */
        private static boolean blockCacheDisabled = false;
      
        /**
         * Returns the block cache or <code>null</code> in case none should be used.
         *
         * @param conf  The current configuration.
         * @return The block cache or <code>null</code>.
         */
        private static synchronized BlockCache instantiateBlockCache(){
           // initiate globalBlockCache
