> In metric v1, the JvmMetrics isn't registered as a bean and so the metrics are not exported to JMX.
> The metric v1 is deprecating but currently hbase still relies on it. It results in that we could get jvm metrics by accessing /metrics on hmaster/regionserver's info port, but can't by accessing /jmx. This issue tries to fix it.
