Re: Failed to start Cloudera Manager Agent

There is an issue with the hostname you have configured on the host.

Can you make sure that "hostname -f" resolves to a valid FQDN?

Re: Failed to start Cloudera Manager Agent

Thank you, I had mentioned alias in front of hostname in /etc/sysconfig/network file. i removed alias issue resolved .. hostname -f command helped me identify the issue
