Setting up a second cluster and getting a weird issue

[Andrew Nguyen]

I'm working on bringing up a second test cluster and am getting these 
intermittent errors on the DataNodes:

2010-05-12 17:17:15,094 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode:

There are 4 slaves and sometimes 1 or 2 have the error but the specific nodes 
change.  Sometimes it's slave1, sometimes it's slave4, etc.

Any thoughts?

Thanks!
