Namenode formatting problem
This is Hadoop 2.0.  Formatting the namenode produces no errors in the shell, but the log shows this:

No java processes begin (although I wouldn't expect formatting the namenode to start any processes, only starting the namenode or datanode should do that), and "hadoop fs -ls /" gives me this:

ls: Call From [CLIENT_HOST]/127.0.0.1 to [MASTER_HOST]:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

My /etc/hosts looks like this:
127.0.0.1   localhost localhost.localdomain CLIENT_HOST
MASTER_IP MASTER_HOST master
SLAVE_IP SLAVE_HOST slave01

This is on EC2.  All of the nodes are in the same security group and the security group has full inbound access.  I can ssh between all three machines (client/master/slave) without a password ala authorized_keys.  I can ping the master node from the client machine (although I don't know how to ping a specific port, such as the hdfs port (9000)).  Telnet doesn't behave on EC2 which makes port testing a little difficult.

Any ideas?
