public class HBaseMetrics2HadoopMetricsAdapter
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.
