> Prerequisite Checks
> When the user clicks on "Enable NameNode HA", we will perform the following checks:
> * If the cluster consists of less than 3 hosts, display the error message in a popup: "You must have at least 3 hosts in your cluster to enable NameNode HA".
> * If the above check passes and if the cluster consists of less than 3 ZooKeeper Servers, display the error message in a popup: "You must have at least 3 ZooKeeper Servers in your cluster to enable NameNode HA".
> * If the above check passes and if the cluster is already secure, display the error message in a popup: "You cannot enable NameNode HA via this wizard as your cluster is already secured. First, disable security by going to Admin > Security, and then run this Enable NameNode HA wizard again. After NameNode HA is enabled, you can go back to Admin > Security to secure the cluster."
> The user cannot proceed forward in case any of the above errors have been encountered.
