4. Manually Redeploy Cluster Topologies

When the gateway properties or gateway-wide settings are changed, you must manually redeploy the clusters. Redeploy cluster topologies after changing the following:

  • Time settings on the gateway host

  • Implementing or updating Kerberos

  • Implementing or updating SSL certificates

  • Changing a cluster alias

[Tip]Tip

Updating cluster properties does not require you to manually redeploy clusters. Cluster topology descriptor files are in the /etc/knox/conf/topologies directory and the corresponding deployment is in /var/lib/knox/data/deployments . The gateway monitors the topology directory for changes. If the descriptor changes or a new one is added, the gateway automatically redeploys the cluster.
