Hi,
Please see my patch for this issue. I just simply removed it since it's
redundant.
Update: not sure why I cannot upload the patch file. Should I send an email
instead of upload patch here? thanks.

> [metrics] Ill-formatted numRegions metric in
> "Hadoop:service=HBase,name=RegionServer,sub=Regions" mbean
> -------------------------------------------------------------------------------------------------------
>
> Key: HBASE-20233
> URL: https://issues.apache.org/jira/browse/HBASE-20233
> Project: HBase
> Issue Type: Bug
> Components: metrics
> Reporter: stack
> Priority: Trivial
> Labels: beginner
>
> Noticed this poking at metrics. The MBean
> "Hadoop:service=HBase,name=RegionServer,sub=Regions" carries per region
> metrics. They are all formatted like so:
> {code}
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_98th_percentile:
> 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_99th_percentile:
> 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_99.9th_percentile:
> 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_num_ops:
> 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_min: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_max: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_mean:
> 0,
> {code}
> In the middle of them all is a metric named...
> {code}
> numRegions: 15,
> {code}
> It has a different format and it is out of scope when compared to the other
> metrics in this mbean; it belongs better elsewhere, perhaps in the Server
> bean.
> I noticed it because it breaks the parse done by tcollector scraping our
> metrics from /jmx
> It was added long ago in HBASE-14166
