Subject datanode's Periodic error
Date Fri, 20 Nov 2009 00:47:17 GMT
Hi 

We have a hadoop cluster using hadoop-0.20.0 running centos5.2.
Now I get periodic error every five minutes from all datanodes.

2009-11-19 15:54:52,077 ERROR
org.apache.hadoop.hdfs.server.datanode.DataNode:

Can you give me any advice.

Thanks
