    Is there any way to configure some of the currently “hidden” hadoop parameters, for example;

    dfs.http.address
    mapred.job.tracker.http.address
    mapreduce.history.server.http.address

    We have two nic’s in our servers and the default value HDP is setting for these parameters is causing the port to be open on the wrong interface. I can’t set the values in Ambari because while they aren’t exposed they can’t be set in the custom fields either. Is there some other way to configure them in Ambari or via a db/config?

    Additionally I need the task trackers to run JDK1.7, similar to the previous problem I can manually set the JAVA_HOME value in the hadoop-env.sh on each node, but it gets rewritten with each server restart. Can I control that value via Ambari or some config on the Ambari server?

    Thanks
    Erik

    Eric,
    not in the current release…
    You can change all things directly in the config files, but then you should not use Ambari for management tasks (stop/start) as it will revert all the changes.

    Sorry for inconvenience….
