I have setup an autoscaling group in Amazon for my Elasticsearch Cluster.
Everything was working fine with the discovery and all.
I currently have 2 instances in the AutoScaling group. I started to work on
a new Elastic Load Balancer health check, but since it's not done yet, the
check only pass for 1 node and the other is terminated every 3000 seconds.
My cluster is configured with the default settings, 5 shards, 1 replica. So
in theory, when 1 node is terminated, the fist one should keep all the data
and automatically know that it's alone in the cluster. When a new node is
spawned, it will automatically add it and sync.
During the WE, this continued to happen, but I'm now in a situation where
my cluster is in a bad state, my indexes doesn't have 5 shards but 3,
Elastic HQ plugin tells me there's more than 2 nodes, unassigned shards.
This test cluster doesn't have any data, less than 1000 documents, so the
replication time is minimal.
What do you recommend ?
