title: how to test redis cluster
body: <p>I have a Redis cluster with 3 masters. 
  I am not interested in data persistence since this is a caching solution. 
  I am running v3.2 on Windows.
  When I stop one of the servers manually to see if I can still access the db, I get 'CLUSTERDOWN The cluster is down error'.
  And even to do that, I have to connect to one of the instances that is still working.
  I don't see how this is a solution for high availability.
  I hope that I am missing something.
  Any ideas why I can't access the cluster when one of the nodes is down?
  Thank you.</p>
  
  <p>Cluster create command:ruby.exe redis-trib.rb create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002</p>
