Hello all, I ran into an issue when installing the CDH cluster. I'm trying to install on a single machine. I selected the machine, parcels and am trying to do it as root. At the end of the installation I receiving the following error messages: "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)." I've found this error in some other forums and attempted to make the changes suggested in those places. These are the contents of my hosts file (I've also tried it with the localhosts line commented out). 127.0.0.1 localhost 192.168.xx.xx FQDN # 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 This is my netstat for the port, I assume it's just Cloudera Manager listening. I did specifically open the port on the firewall. netstat -ntlp | grep :7182 tcp 0 0 0.0.0.0:7182 0.0.0.0:* LISTEN 1861/java Here are the contents of cloudera-scm-agent.out: [29/Aug/2013 10:24:31 +0000] 2867 MainThread agent INFO SCM Agent Version: 4.6.3 [29/Aug/2013 10:24:31 +0000] 2867 MainThread agent ERROR Could not determine hostname or ip address; proceeding.

I also have the cloudera-scm-agent.log if that would be helpful. The only errors that I see in there are: [28/Aug/2013 11:58:13 +0000] 25640 MainThread agent ERROR Failed to connect to newly launched supervisor. Agent will exit . . .

Thank you, Meredith
