Subject [jira] [Commented] (HDFS-2244) JMX values for RPC Activity is always zero
Date Wed, 10 Aug 2011 23:59:28 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082777#comment-13082777

Allen Wittenauer commented on HDFS-2244:
----------------------------------------

I'd be surprised, but maybe that is the case.  I've been running teragen and terasort so I'd
expect that to trigger something?

> jconsole is showing that the RPC metrics gathered for the datanode is always zero.  Other
metrics for the DN appears fine.
