hi Mohammad Tariq,
thanks for reply. I follow your instruction, change the hosts to this: master: 127.0.0.1 localhost 127.0.0.1 localhost ubuntu 10.66.201.243 master 10.66.201.244 slave1 10.66.201.245 slave2 slave1: 127.0.0.1 localhost 127.0.0.1 slave1 ubuntu 10.66.201.243 master 10.66.201.244 slave1 10.66.201.245 slave2 slave2: 127.0.0.1 localhost 127.0.0.1 slave2 ubuntu 10.66.201.243 master 10.66.201.244 slave1 10.66.201.245 slave2 It still doesn't work. the same problem. The regionserver try to connect to localhost:60000. And the hmaster still start at localhost:60000.
