[jira] [Created] (HADOOP-9180) Export JVM metrics via JMX

Hangjun Ye created HADOOP-9180:
----------------------------------

             Summary: Export JVM metrics via JMX
                 Key: HADOOP-9180
                 URL: https://issues.apache.org/jira/browse/HADOOP-9180
             Project: Hadoop Common
          Issue Type: Improvement
          Components: metrics
    Affects Versions: 2.0.2-alpha
            Reporter: Hangjun Ye
            Priority: Minor
             Fix For: 3.0.0


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.
