As a student we were asked to implement a cloudier cluster using Vm’s , i tried to install cloudier cluster using 3 Vm’s under ubuntu 14.01 , My steps so far : I used ssh passwordless connection between all nodes , (tested ) Configure /etc/hosts to all my vm’s installed cloudera CDH , the problem occurs when i try to install every thing on each node this thing occurs .enter image description here
but whats make me so unconfident about this its it identify perfectly my hosts names and address in the pre-installation [enter image description here][2] enter image description here but when i try to install it fails and give me the error mentioned , so i tried to see if python dont recognize my hostnames so i went on some codes to test and every thing worked perfectly :
>>> import socket
>>> socket.gethostbyname("master1")
'10.211.55.13'
>>> socket.gethostbyname("slave1")
'10.211.55.11'
>>> socket.gethostbyname("slave2")
'10.211.55.12'
>>>
my /etc/hosts file its similar to all hosts
127.0.0.1 localhost
#127.0.1.1 ubuntu
10.211.55.13 master1.bdsas.com master1
10.211.55.11 slave1.bdsas.com slave1
10.211.55.12 slave2.bdsas.com slave2
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
CDH does not support IPv6 (see this link: https://www.cloudera.com/documentation/enterprise/5-8-x/topics/cdh_ig_req_supported_versions.html) and search for IPv6. Turn off IPv6 in your network configuration and see if that resolves the issue.
