@InterfaceAudience.Private
public class HBaseMetrics2HadoopMetricsAdapter
extends Object

This is the adapter from "HBase Metrics Framework", implemented in hbase-metrics-api and hbase-metrics modules to the Hadoop Metrics2 framework. This adapter is not a metric source, but a helper to be able to collect all of the Metric's in the MetricRegistry using the MetricsCollector and MetricsRecordBuilder. Some of the code is forked from https://github.com/joshelser/dropwizard-hadoop-metrics2.
