Subject [jira] [Commented] (HBASE-5862) After Region Close remove the Operation Metrics.
Date Thu, 26 Apr 2012 18:10:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5862?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262808#comment-13262808
] 

Zhihong Yu commented on HBASE-5862:
-----------------------------------

{code}
+    //per hfile.  Figuring out which cfs, hfiles, ...
{code}
Should cfs be in expanded form (column families) ?
{code}
+    //and on the next tick of the metrics everything that is still relevant will be
+    //re-added.
{code}
're-added' -> 'added' or 'added again'

The initialization work in clear() should be moved to RegionServerDynamicMetrics ctor because
it is one time operation.
