Hi, Cluster consists of 13 nodes which have one server as a Knox Gateway (G1). I have added another hosts (for naming convention, let's call this G2), which has the same configuration of original Knox Gateway (G1). I have basically copied every Knox file I have from G1 to G2. My purpose is to transfer some of the services to G2 without having a downtime that's why I wanted them both to be started at the same time. However, upon starting Knox Gateway Service on G2, i get an error like this: 2018-10-05 14:03:45,730 - call['ambari-sudo.sh su knox -l -s /bin/bash -c 'curl --location-trusted -k --negotiate -u : -b /var/lib/ambari-agent/tmp/cookies/97b20bd8-6a80-4926-a259-5e0d1c7bc8b3 -c /var/lib/ambari-agent/tmp/cookies/97b20bd8-6a80-4926-a259-5e0d1c7bc8b3 '"'"'http://hostname:6080/service/public/v2/api/service?serviceName=ATOM_knox&serviceType=knox&isEnabled=true'"'"' --connect-timeout 10 --max-time 12 -X GET 1>/tmp/tmpdUkhUB 2>/tmp/tmpqBAJxt''] {'quiet': False, 'env': {'KRB5CCNAME': '/var/lib/ambari-agent/tmp/curl_krb_cache/ranger_admin_calls_knox_cc_1798c3584893e89264ef19583301540be127e51c242bfc943fe8a207'}} 2018-10-05 14:03:45,837 - call returned (0, '') 2018-10-05 14:03:45,837 - Will retry 4 time(s), caught exception: Error in call for getting Ranger service:

Is it possible to setup 2 knox gateway with the same files and start them at the same time? Please help.
