    Hi fellows Ambarists

    If I’m not wrong, in hadoop the default conf of dfs.namenode.http-address is 0.0.0.0:50070.

    Ambari configured my cluster with this value : namenode1.poc-hadoop.xxxxxxx:50070, which happens to be resolved to the ip address in the internal LAN of the cluster, making this unreachable from the outside of the cluster.

    My questions :
    1/ Why Ambari does not keep the default of 0.0.0.0 ?
    2/ Where should I update this in Ambari ? In Custom hdfs-site.xml ?
    3/ I suppose I have to do that for all the web UIs of all the services ? How can I change this quickly ? I like the Ambari UI, but not enough to customize a dozen of properties manually…

    Thanks for your help
    Mathieu
