Subject RE: Error in 9000 and 9001 port in hadoop-0.20.2
Date Thu, 28 Jul 2011 14:25:50 GMT
Start the namenode[set fs.default.name to hdfs://192.168.1.101:9000] and
check your netstat report [netstat -nlp] to check which port and IP it is
binding. Ideally, 9000 should be bound to 192.168.1.101. If yes, configure
the same IP in slaves as well. Otw, we may need to revisit your configs
once. 

To use the hostname, you should have hostname-IP mapping in /etc/hosts file
in master as well as slaves.
