Subject java.lang.IllegalArgumentException: Duplicate metricsName:getProtocolVersion
Date Wed, 14 Oct 2009 11:50:33 GMT
Hi all,

Using hadoop 0.20.1 I am seeing the following on my namenode startup.

  2009-10-14 11:09:54,232 INFO org.apache.hadoop.ipc.Server: Error
register getProtocolVersion
      java.lang.IllegalArgumentException: Duplicate
metricsName:getProtocolVersion

Could someone please point me in the right direction for diagnosing
where I have gone wrong?

Thanks
Tim
