Subject 0.20.1 Cluster Setup Problem
Date Tue, 13 Oct 2009 14:17:14 GMT
Hi,


We are trying to set up a cluster (starting with 2 machines) using the  
new 0.20.1 version.

On the master machine, just after the server starts, the name node  
dies off with the following exception:

2009-10-13 01:22:24,740 ERROR  
org.apache.hadoop.hdfs.server.namenode.NameNode: java.io.IOException:

Can anyone help ?  Also can anyone send across example configuration  
files for 0.20.1 if they are different than we are using ?

The detail log file is attached along with.
