Duo Zhang updated HBASE-28327:
------------------------------
Component/s: metrics
> Add remove(String key, Metric metric) method to MetricRegistry interface
> ------------------------------------------------------------------------
>
> Key: HBASE-28327
> URL: https://issues.apache.org/jira/browse/HBASE-28327
> Project: HBase
> Issue Type: Improvement
> Components: metrics
> Reporter: Evelyn Boland
> Assignee: Evelyn Boland
> Priority: Major
> Fix For: 2.6.0, 2.5.8, 3.0.0-beta-2
>
>
> Add a `remove(String name, Metric metric)` method to the `MetricRegistry`
> interface. Right now the interface only contains a `remove(String name)`
> method.
> This additional remove method will give users the power to remove a `Metric`
> with the specified `name` from the metric registry if and only if the
> provided `metric` matches the object in the registry.
> Implementing the new `remove(String name, Metric metric)` should be straight
> forward because the `MetricRegistryImpl` class stores metrics in a
> `ConcurrentMap`, which already contains a `remove(Object key, Object value)`
> method
> This change will not be a breaking one because the interface is marked with
> `@IntefaceStability.Evolving`
