Description

Since the building blocks to retrieve the RegionServer/DataNode profiling data is done (in Facebook's HDFS branch – the changes are/will be posted to Github soon), it would be great to integrate them together, so that the HBase client can not only get the RegionServer metrics but also the DataNode status. It will offer the client a much clear view from end to end perspective including the disk/network level detail information for each request.
