I have a 3 node cluster:
node master: true
My questions are these:
The Node 3 (just master, not data) should be dedicated master or dedicated voting-only master ???
When I see the shard distribution on both data nodes (nodes 1 and 2), I can see a shard balancind around 20%, I say Node 1 has 80% primary shards and 20% replica shards, and Node 2 has 20% primary shards and 80% replica shards. I've supposed the shard distribution should be 50% primary and 50% replica in each nodes. Can you explain to me?
Special thanks and greetings!!!
