Hi, Lets say I have a 3 node cluster and I deploy one index SPECIFIC to every data node in the cluster. So, index1 goes to node1, index2 goes to node2, etc. using the routing.allocation settings based on node.zone etc. config properties. There may be 5-6 shards per index, but no replicas. All three indices, index 1/2/3 will have the same mapping schemas.
Now, if the following scenarios occur: 1.] One node, node2, goes down: How can I get the node 2's index, index2, live on the other two data nodes? Can I just copy the data directory to the other nodes? Since there is no mapping like index2 defined on those nodes, will I have to first create the mapping there? Can I move half the shards to each remaining node? 2.] Assume one more node is now added to this cluster: Can I copy the mapping schema to the new node and selectively copy 1-2 shards each from the existing 3 data nodes so that I can rebalance the cluster 3-4 shards per index per node? I am not sure if there is this level of control and how it is exposed. Please let me know.
