Solr and Zookeeper Configuration -


in production environment, should solr setup on every server possible including 1 having zookeeper? talking external zookeeper

total servers : 5

case 1: solr on 5 servers. zookeeper on 3 servers.
case 2: solr on 2 servers. zookeeper on 3 servers.
case 3: solr on 5 servers. zookeeper on 5 servers.

what best practice? advantages of using 1 case on another? have read it's better have zookeeper in separate server.

at point of time zookeeper instance should in 2n+1 count. in case can go maximum 5 since have 5 servers. i.e. solr on 5 servers , zookeeper on 5 solr servers. original sizing can determined based on index size,query complexity, approximate query hit count minute , compromised result time.
