| collection of MetricsMutables, making writing metrics source easier. |
| NOTE: this is a copy of org.apache.hadoop.metrics2.lib.MetricsRegistry with added one |
| feature: metrics can be removed. When HADOOP-8313 is fixed, usages of this class |
| should be substituted with org.apache.hadoop.metrics2.lib.MetricsRegistry. |
| This implementation also provides handy methods for creating metrics |
| dynamically. |
| Another difference is that metricsMap implementation is substituted with |
| thread-safe map, as we allow dynamic metrics additions/removals.</div> |
