Hi everyone.
This is my first post on this mailing list and I hope I won't do any
mistakes ;)
I work for a French telecom operator ad we have recently started a
Hadoop project.
We currently have two clusters:
-a preproduction cluster running with 1 master plus 4 nodes
-a production cluster running with 1 master plus 24 nodes
Both clusters are running Hadoop 0.20.2 and the jobs are running smoothly.
However, on every datanodes of each cluster I receive, every 5 minutes,
I see this error :
2010-10-04 14:31:46,564 ERROR
org.apache.hadoop.hdfs.server.datanode.DataNode:

And I can't find anything on the web ...
Anyone has a clue ?
