Objective: WIth this procedure, we want to replace node 172.31.1.23 with node 172.31.7.30. Also, it is required that we change exhibitor_zk_path to something unique in order for this procedure to work.
Configure the bootstrap node with the modified config.yaml that has a change to a new exhibitor_zk_path along with the master node that you want to replace for master_list
Important NOTE: The most important piece is exhibitor_storage_backend: zookeeper and exhibitor_zk_path: "/masterip-change-20170127". You must set exhibitor_zk_path to be something unique otherwise your cluster wont converge.
