FAQ
I have a single node cluster CDH4 installation. The IP address of my laptop
is not static, and it got changed.
Now it says that the health of the host is Bad, no host heartbeat,


How can I edit the IP address of a host once it is part of a CDH4 cluster?

    Hello,

    You can try this steps to change ip address on CDH.

    1) stop all the cloudera manager agents in all the clusters
    2) stop the cloudera manager server and server db service in the scm server
    (namenode server)
    3) Modify /etc/cloudera-scm-agent/config.ini to point to the new scm server
    ip (namenode server ip)
    4) In /etc/hosts file add your new ip address and hostnames
    5) Start all the services 1 by 1 from server-db, server, agent and you can
    see the ips got changed in the Host on cloudera

    you can see the same issues on this url
