------------------------------------

Hey Kannan. We have an intern here who is also working on something similar to this. Do you have any docs on the plan? Would be good to collaborate where possible.

> 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.]
