Subject [jira] [Commented] (HBASE-5862) After Region Close remove the Operation Metrics.
Date Thu, 26 Apr 2012 18:16:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5862?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262813#comment-13262813

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.
