      Metrics names are standardized to use CapitalizedCamelCase. Some examples of this is:
      # Metrics names using "_" is changed to new naming scheme. Eg: bytes_written changes to BytesWritten.
      # All metrics names start with capitals. Example: threadsBlocked changes to ThreadsBlocked.

    Description

      The jira tracks the metrics instrumentation for the new framework, i.e., porting jvm and rpc metrics to the new framework.

      This issue (esp. the "incompatible change flag") depends on the outcome of the discussion (proposed in HADOOP-6728) on whether we should support backward compatibility (at some cost.)
