    Hello,

    I have a cluster with 24 datanodes : I have used Ambari to install 12 servers.
    Now, I have 12 more servers : can I use to update the cluster to take into account the new datanodes ?
    In Ambari, I can’t see any buttons or links to update the configuration of my cluster.

    Thanks for any help !

    Bruno

    Login into Ambari -> Browse to “Hosts” -> You should see a “Add New Hosts” button.

    This will popup a wizard (similar to the initial cluster install wizard) to add new hosts.
