Solved the issue,   It was the etc/hosts file causing issue.   Had to add the highlighted red text on the etc/hosts file   127.0.0.1   localhost.hadoopdomain localhost ::1         localhost.hadoopdomain localhost 127.0.0.1   localhost.localdomain localhost 127.0.0.1   localdomain localhost 192.168.1.8 base.hadoopdomain.com base base.hadoopdomain 192.168.1.6 node1.hadoopdomain.com node1 node1.hadoopdomain 192.168.1.7 node2.hadoopdomain.com node2 node2.hadoopdomain     Regards, Pranay Vyas     ...

Samuel,   Can you try a ping from your node  - ping google.com see if your node has access to internet.   Cloudera Manager during its installation process refers to Interenet to download various components.   Regards, Pranay Vyas ... View more

Solved it. The issue was with /etc/hosts file.   For some reason the Cloudera Manager was referring to localdomain which was not part of my /etc/host file   Had to add highlighted red texts on /etc/host file to resolve this error.     127.0.0.1   localhost.hadoopdomain localhost ::1         localhost.hadoopdomain localhost 127.0.0.1   localhost.localdomain localhost 127.0.0.1   localdomain localhost 192.168.1.8 base.hadoopdomain.com base base.hadoopdomain 192.168.1.6 node1.hadoopdomain.com node1 node1.hadoopdomain 192.168.1.7 node2.hadoopdomain.com node2 node2.hadoopdomain   Regards, Pranay Vyas   ...

Okay, I was able to pass through the dns issue and changed the nsswitch on all nodes to files dns. I uninstalled CLoudera manager and started all again.   It failed with the same error. Installation failed. Failed to receive heartbeat from agent. Ensure that the host's hostname is configured properly. Ensure that port 7182 is accessible on the Cloudera Manager server (check firewall rules). Ensure that ports 9000 and 9001 are free on the host being added.   [Errno 99] Cannot assign requested address on ('base.hadoopdomain', 9000) -- [Errno 99] Cannot assign requested address   The Python socket command still give incorrect IP [root@base ~]# python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())' base.hadoopdomain 198.105.254.228   It gives same IP on all the nodes. THe FQDN comes correctly.   Regards, Pranay Vyas   ... View more

How did you solve the DNS issue.  When I ran the Python command the FQDN is correct, but I get a 198 IP. I dont know where this is coming from.    I have a 3 node cluster and hosts file defined correctly on all 3 nodes. The Python returns incorrect IP on all 3 nodes.  python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())' node2.hadoopdomain 198.105.254.228   while the node is is on 192.168.1.6 IP.   Any ideas?   Thank You,  Pranay Vyas ...
