What is the recommend installation procedure for LucidWorks Search cluster? I want high availability.
LucidWorks Search has three components - Core, Connectors and UI.
The current recommendation is to install one "Connectors" and one "UI" process. Both components should sit on different instances in your cluster.
You need to install the core component on a server, and on the 'n' other servers where your core component replicas will run.
For ZooKeeper the recommended ensemble size is 3.
