Subject Error in 9000 and 9001 port in hadoop-0.20.2
Date Thu, 28 Jul 2011 11:52:16 GMT
Hi,

I run Hadoop in 4 Ubuntu 11.04 on VirtualBox.
On the master node (192.168.1.101), I configure fs.default.name = hdfs://
127.0.0.1:9000. Then i configure everything on 3 other node
When i start the cluster by entering "$HADOOP_HOME/bin/start-all.sh" on the
master node
Everything is ok, but the slave can't connect to the master on 9000, 9001
port.
I manually telnet to 192.168.1.101 in 9000, 9001. And the result is
"connection refused"
Then, i'm on the master node, telnet to localhost, 127.0.0.1:9000. The
result is connected.
But, on the master node, i telnet to 192.168.1.101:9000 => Connection
Refused

Can somebody help me?
