Package org.apache.hadoop.hbase.regionserver.wal

Class MetricsWALSourceImpl

java.lang.Object

org.apache.hadoop.hbase.metrics.BaseSourceImpl

org.apache.hadoop.hbase.regionserver.wal.MetricsWALSourceImpl

All Implemented Interfaces:

BaseSource, MetricsWALSource, org.apache.hadoop.metrics2.MetricsSource

@Private
public class MetricsWALSourceImpl
extends BaseSourceImpl
implements MetricsWALSource

Class that transitions metrics from MetricsWAL into the metrics subsystem. Implements BaseSource through BaseSourceImpl, following the pattern.
