Description

Ranger Admin runs in HA mode and knox is configured with:

<provider>
         <role>ha</role>
         <name>HaProvider</name>
         <enabled>true</enabled>
         <param>
            <name>RANGERUI</name>
            <value>maxFailoverAttempts=3;failoverSleep=1000;enabled=true</value>
         </param>
      </provider>

 <service>
    <role>RANGERUI</role>
    <url>http://ip-10-0-2-243.eu-west-1.compute.internal:6080</url>
    <url>http://ip-10-0-2-10.eu-west-1.compute.internal:6080</url>
 </service>

Knox keeps redirecting to the login page. In Ranger log I can see however the login was successful so it accepted the credentials. Load-balancing works as I stop one of the Ranger Admins I still can reach the UI, but cannot move on from the login page. Might be some session issue.

Attached the knox topology and log file and ranger aggregated log.

Ranger is installed with Ambari through Blueprints (see attachment)
