Subject [jira] Commented: (HBASE-2146) RPC related metrics are missing in 0.20.3 since recent changes
Date Tue, 19 Jan 2010 19:24:54 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802423#action_12802423

Lars George commented on HBASE-2146:

Hmm, I checked both cluster then they have the exact same hadoop-metrics, hbase-env and so
on. All diff"ed by my a few times. So why is that cluster different. What is even weirder
is that these are MetricsTimeVaryingRate instances so they must be declared and put into the
MetricsRegistry before createMBean() is called. And I cannot find where that is done!
