Should I build 3 independent ZK emsembles of 7-9 nodes each or is it okay to have one 7-9 node ensemble being shared by Kafka, Solr and Storm? Since the actual utilization of memory & CPU seems quite little per node, for simplicity of deployment it seems having 1 ensemble should be okay since 2-3 nodes will be in separate availability zones in the data center so total failure should not be a common occurence. Thoughts or experiences? thanks, Ayon --001a1144c102287db7052f3ddd37--
