No socket could be created on 9000 -- [Errno 99] Cannot assign requested address

[#1]

Hi

I am installing latest Cloudera Express Edition on Azure using Ubuntu trusty 14.04 LTS. i am getting this error.

/etc/hosts is having public IPs defined in it. The dig command is able to forward lookup, the revese lookup is not working properly. All the ports are open in Azure portal. I kills the 9001 everytime i re-try the installation. The SCM agent is waiting for heartbeat.

This is frustrating. I have followed and crosschecked various links in this forum. Nothing is working. Kindly suggest how to resolve this.

I have ran into this when the host file was incorrect. You said reverse lockups are not working, they should be.

Are you seeing an error in the CM Agent logs? Can you post your hosts file, mask it if needed?

hi

I have resolved this by keeping /etc/hosts with only localhost entries

a) updating listening host and Ip in config.ini of all nodes

it worked
