Deprecated.
Use hbase-metrics/hbase-metrics-api module interfaces for new metrics. Defining
BaseSources for new metric groups (WAL, RPC, etc) is not needed anymore, however,
for existing
BaseSource implementations, please use the field named
"registry" which is a MetricRegistry instance together with the
HBaseMetrics2HadoopMetricsAdapter . |
