Himself has built on it the Hadoop cluster, the configuration of the following hosts file
192.168.1.21 instance01
192.168.1.22 instance02
192.168.1.23 instance03
192.168.1.24 instance04
192.168.1.27 instance05
192.168.1.28 instance06

Above IP is a network IP, before using floatingip unable to start the hadoop

now the question is: hadoop a service port (such as the management interface of HDFS 192.168.1.21:50070), the network can be normal visit, outer net ping can pass but not through a Telnet access to, but it can be accessed, 22, port is the need to set up? (firewall has been closed)

/root @ instance01 ~ # netstat tlun
An Active Internet connections (only the servers)

could you tell me the original poster to solve this problem, I also met the same problem

Can see the inside of the firewall and dashboard network strategy, time is too long, the details don't remember clearly
