> We use FileIOEngine to store and read block data in BucketCache. Before stop RS, the BucketCache metrics in WebUI is like before_RS_restart.png, the block count is 3. When stop RS, the backing map is persistent to file. And then start RS, the metrics is like after_RS_restart.png, the block count is 0, but the size of blocks is correct.
