Hadoop Cluster failed on AWS using cloudera manager.

Hi All,


The Error I'm getting is

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).
  • Ensure that ports 9000 and 9001 are free on the host being added.
  • Check agent logs in /var/log/cloudera-scm-agent/ on the host being added (some of the logs can be found in the installation details).

And my host files details here


ubuntu@ip-10-203-134-227:/var/log$ cat /etc/hosts localhost master slave1 slave2

# 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
ff02::3 ip6-allhosts
Internal Ip details:

Disabled the firewall by using the following command:

 sudo ufw disable

Can you try pinging the hostname from hostname and see you get any response ?

I fixed the issue by adding ipaddress,fully qualified name and hostname in the etc file and also in AWS has two IP'S one is public ip and other is internal ip.In the host file need to write internal ip.Anyway thanks a lot for your reply
