Hi guys,
I need an urgent help to setup Elasticsearch cluster on Amazon EC2
instances as I have to launch an application within a week. I'm trying this
for the last three days without success. I tried to follow many
instructions, created instances all over again and still nothing. I can
telnet instances on 9300. I added security group ES2 having a port range
0-65535 and also individual instances by private IP addresses with range
9200-9400. Nodes can't discover each other,and it seems that both nodes are
created on their own regardless the fact that cluster node info indicates
that good elasticsearch.yml is used. For example, cluster name is the one I
added in elasticsearch.yml, but node name is generic one.
I hope somebody will have some idea if I missed something here.
Here are other details:
My IAM policy is:
