[jira] [Resolved] (HBASE-11854) MetricsRegion.updateScanNext takes 20% of overall RegionScannerImpl.nextRaw call

     [ https://issues.apache.org/jira/browse/HBASE-11854?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Purtell resolved HBASE-11854.
------------------------------------
       Resolution: Duplicate
    Fix Version/s:     (was: 0.98.7)
                       (was: 2.0.0)
                       (was: 0.99.0)
         Assignee:     (was: Vladimir Rodionov)

I'm going to resolve this as a dup of HBASE-11876 because there's a patch available on that issue and it seems to subsume this.
