We are planning to run Elasticsearch 1.7 with Java 7 version and we have 3 Physical Servers.
Our proposed setup is as follows:-
a. 3 Master Nodes (1 in each server)
b 3 Client Nodes (1 in each server)
c. 3 Data Nodes (1 in each server)
So, in total, we are planning to have 9 Nodes running from 3 Physical Servers and our servers have 128 GB RAM
We understand 50 % of RAM size (64 GB) is used by OS and
1. We would like to know the recommended value for ES_HEAP_SIZE for Master node, Client node & Data node respectively?
