Hey,

Check if firewall is running that might create problem for the installation.

Please send vendor specific questions to that vendor's support mechanism.

Since your issue appears to be with Cloudera Manager, please use http://community.cloudera.com/<https://urldefense.proofpoint.com/v2/url?u=http-3A__community.cloudera.com_&d=AwMFaQ&c=aIUDzRSH0GV4AQi9KEcOBQ&r=Q6FqyTxAatyPFtTsK6ghgTPkJfjL8rxaHWBrAFzranM&m=1jJIxa1X-SkcZeaCo0M-WlyX1peqQKxCuWyzgUJvP1Q&s=-2aTyiJDKALsZBR88RlkVyf4ILC5rIdwBPTSJxMo1Nk&e=>

The below script also giving the correct result i.e. correct hostname and ip address.
python -c 'import socket; print socket.getfqdn (), socket.gethostbyname (socket.getfqdn ())'


Not sure what else to look for.

Please guide.

Thanks

Krish
