Ok, since the master doesn't contain any data, and don't do lot ofs IOs: For 8GB RAM, what's the recommended HEAP_SIZE ? 7GB
and i don't fully understand the client (query management node). Today, i have set node.master=true and node.data=true. and with new master only, i will have masters only nodes and data only nodes. What the correct setting for client node ? node.client=true (with node.master=false and node.data=false) with http adress set ? so i don't need to tell the masters adress to the other applications like logstash, tomcat, ... ?
