Hell team - I'm in a situation where i need to upgrade ES1.x to ES6.2, I have installed ES6.2 nodes equal no of number as OLD ES cluster ( 3 Data nodes and 3 Master nodes) My question: 1.How can i include the reindex.remote.whitelist in the new ES nodes which should include the all the 3 data and 3 master. reindex.remote.whitelist: ["DATA1:9200","DATA2:9200","DATA3:9200","MASTER1:9200","Master2:9200","Master:9200"] 2.should i include this setting variable in all the master and data nodes in the new cluster? 3.. How can i provide the shard and replica settings to entire ES cluster. ---
