Review your topologies. If you prefer to use the new topologies, copy the topology templates to the active topologies directory:

cp /usr/hdp/current/knox/templates/topology.xml /usr/hdp/current/knox/conf/topologies/{clustername}.xml

Modify the topology to match the cluster resources in your deployment.

Create the Master Secret:

su - knox -c “/usr/hdp/current/knox/bin/knoxcli.sh create-master”

Start the Gateway:

su -l knox -c "/usr/hdp/current/knox-server/bin/gateway.sh start"

Check /var/log/knox/gateway.log for errors or successful start.
