The health is yellow. I have a 2 node cluster for Elastic search and the health is in yellow. It looks like there are 10 primary shards and 2 replicas (i.e 2 reaplicas per primary shard so that mean 20 replica shards). If primay is in node1 and can all the replicas be in node 2 or will we need a node 3 for the second replica. I did read that ES does not place replica in the same node as the primay. so does if there a 2 replicas can it place in the same node (node2) or the second one has to be place in node 3

If you want 3 copies of a shard (1 primary and 2 replicas) you need 3 nodes at least.
