Using ES 1.4.3 and Java 1.8\_31 4 servers of 32core, 128GB RAM, 4TB data So 128 cores, 512GB RAM, 16TB data total Two questions... Question 1- Because I have such "wonderful" machines I have decided to run dedicated master nodes on the same physical machines as the data nodes running in same OS instance but separate JVM. Is it even worth it or should I just us default config until I can get real physical machines for masters? So I have... server1:9000 (http of master node) server1:9100 (tcp of master node) server1:9200 (http of data node) server1:9300 (tcp of data node) server2:9000 (http of master node) server2:9100 (tcp of master node) server2:9200 (http of data node) server2:9300 (tcp of data node) server3:9000 (http of master node) server3:9100 (tcp of master node) server3:9200 (http of data node) server3:9300 (tcp of data node) server4:9200 (http of data node) server4:9300 (tcp of data node) Master nodes configured to 4GB of RAM Data nodes to 30GB of RAM Question 2: When running dedicated master nodes, do we configure the clients to connect to the master nodes or to the actual data nodes? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
