Hi Karl, By MCF nodes i mean MCF instances or tomcat servers having MCF webapps deployed.
My current setup is having 6 (3+3) zookeeper instances with both MCF nodes/instances using same zookeeper cluster and one DB instance is managed by two entirely separate MCF instances. Also i am running agent 1 on first node/instance and agent 2 on second node/instance.What i am expecting now is that both MCF instances run in parallel and crawling the source and storing index in Solr or twice the processing power here.
