 <div class="block">Set to specify a custom scope for the metrics published through <a href="MetricsConnection.html" title="class in org.apache.hadoop.hbase.client"><code>MetricsConnection</code></a>. The
  scope is added to JMX MBean objectName, and defaults to a combination of the Connection's
  clusterId and hashCode. For example, a default value for a connection to cluster "foo" might be
  "foo-7d9d0818", where "7d9d0818" is the hashCode of the underlying AsyncConnectionImpl. Users
  may set this key to give a more contextual name for this scope. For example, one might want to
  differentiate a read connection from a write connection by setting the scopes to "foo-read" and
  "foo-write" respectively. Scope is the only thing that lends any uniqueness to the metrics.
  Care should be taken to avoid using the same scope for multiple Connections, otherwise the
  metrics may aggregate in unforeseen ways.</div>
