Is there plan to add possibility to set up HA Knox Gateway in Ambari ?

It will be useful feature.

Or maybe is there an option to configure more than one Gateway ?

Hello

This thread might help : https://community.hortonworks.com/questions/24961/how-to-configure-ha-for-knox-gateway-using-any-loa...

and the knox documentation as well: http://knox.apache.org/books/knox-0-6-0/user-guide.html#High+Availability

As far as ambari is concerned there are plans,but you can always create your own Ambari stack to deploy a second knox and do the work to make it HA.

Adding multiple Knox gateways to respective cluster nodes by Ambari is supported, and has been supported for a while, see details here. You need to set the LB by yourself. Also, you need to sync {GATEWAY_HOME}/conf/security/ folders over all Knox instances, using one of them as a source; this is not done by Ambari.
