I am working on elasticsearch 6.5 and i don't know much about it , so my task is to add cluster node , i guess initially number of node is 1 right? if i am right then please tell me how can i make it up to 6, i already read the documentation but i can't get it, one more suggestion i got to install elasticsearch multiple time and give different node name or something like that but what i feel is there must be some simple way to do it
actually this is the exact requirement that i want:-
Cluster Nodes : 6
Master Eligible Nodes : 2 (both the micro instances). These are Master only nodes.
Data Only Nodes : 4 (2 regular nad 2 preemptible instances)
Number of shards : 8
Number of replica sets : 2
