Elliott Clark commented on HBASE-5862:
--------------------------------------
@lars Yes there's a missing api. Hadoop metrics keeps a copy of all metrics
created. That copy is used to expose the data to jmx and other consumers.
There is no remove function. HADOOP-8313 was filed to correct this. However
until that changes reflection was the only way.
> After Region Close remove the Operation Metrics.
