Question

I got this error

Installation failed. Failed to receive heartbeat from agent.

when I was installing cloudera on single node. This is what is in my /etc/hosts file:

127.0.0.1   localhost

This is what is in my /etc/hostname file:

ubuntu

And this is the error in my /var/log/cloudera-scm-agent file:

Answer 1

I am facing similar problems. I've found how to solve the problem:

ERROR    Failed to collect NTP metrics

It's because NTP service is not installed/started. Try:

sudo apt-get update && sudo apt-get install ntp
sudo service ntp start

Got the same error, please assure that your hostname could be translated to your ip. Run ifconfig -a lookup your ip address for eth0, then run dig or host command using your FQDN and review the ip address is the same that ifconfig shows.
