Ranger and Knox configuration for Ambari for DPS

[#1]

To use DPS services, i.e. DLM, for replication between HDP clusters over wired encryptions leverages the Knox gateway functionality. For that two services must be configured in Knox and one Ranger Policy created. This is the quick setup of the required Ambari services in Knox and Ranger.

Adding two new services (AMBARI and AMBARIUI) to the Knox advance topology configuration

            <service>
                <role>AMBARI</role>
                <url>http://knox-gw:8080</url>
            </service>
            <service>
                <role>AMBARIUI</role>
                <url>http://knox-gw:8080</url>
            </service>

In Ranger define a policy to allow the access to AmbariUI

Then restart the all marked service in the cluster.

Test that it works and login to Ambari by proxying Knox (default port: 8443).

Now you can join the cluster in DPS.
