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

             Summary: hbase client metrics per user specified identity on hconnections.
                 Key: HBASE-27466
                 URL: https://issues.apache.org/jira/browse/HBASE-27466
             Project: HBase
          Issue Type: Improvement
          Components: Client
            Reporter: Victor Li


At present, hbase client metrics is per each individual hconnection and with a pre-configured scope in conf or cluster ID plus connection ID which has generated hash code as suffix. It make the metrics not flexible enough for monitoring if one hbase cluster has multiple clients serving different purposes, we may want to monitoring the hbase client metrics for certain specific clients, each client may have one or more connections.

I am proposing one more attribute to the metrics like connection identity, making the metrics per connection identity and use this connection identification as its scope. The connection identity is provided by hbase user.

If a connection identity is not provided, client metrics will continue working per hconnection and has a connection ID as it scope. I.e. no behavior change.
