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?
