> Add ability to get HBase metrics back from an individual request. Apps can use this to track fine-grained metrics (such as server-side latency, block cache access/hit count; sync latency; append latency; etc.) on a per-API call basis. Also, enhance HBase shell to also support this feature. [For example, if in the shell we turn profiling on, for all subsequent requests the profiling stats will be pretty printed, or optionally written to a file.]
