Hi All, I'm wondering if anyone can see what I may be doing wrong in my ES configuration. A log and the resulting exception follow. Here is a description of the relevant sections: I am deploying to a single large instance on EC2. // Section A - An ES data node is bootstrapped using Spring during the initialization of a web app. // [Grey King] starts successfully, elects itself as a master and the cluster status is green. // Please note that I am setting some sub-properties (i.e. gateway.s3.bucket) even though I set // the gateway.type to none. This makes it easier for me to switch between dev, qa and // production builds without maintaining completely separate configs for each.

Is there anything wrong with my configuration, or perhaps my EC2 configuration has to open additional ports? I am assuming the ports will have to be opened when I start to add additional instances, but this is a single VM. I'm not sure what the potential reasons for a discovery failure on EC2 might be.

I did not see the setting discovery.type on the second non data node, was it there?
