public class MetricsMBeanBase
extends org.apache.hadoop.metrics.util.MetricsDynamicMBeanBase

Extends the Hadoop MetricsDynamicMBeanBase class to provide JMX support for custom HBase MetricsBase implementations. MetricsDynamicMBeanBase ignores registered MetricsBase instance that are not instances of one of the org.apache.hadoop.metrics.util implementations.
