    I am having issues with the connection between ambari Server and host. I am completely new to Linux and any help would be greatly appreciated. I’m using CentOS and a 2 node cluster. Please let me know if I need to provide anymore information.
    Thanks!

    Hi Saraha,

    Are you able to resolve both the hosts using the hostnames?

    Thanks
