Hi, Setup: 3 ubuntu servers installed ES with repository all 3 nodes running ES 2.2.1 I'm running cluster with 3 nodes. One of the nodes has been running as a single node for a long time. Now I added 2 new nodes and they connected to the first node. If I change the first nodes elasticsearch.yml, it can't start again. I don't even get any elasticsearch.log in /var/log Any changes to the elasticsearch.yml breaks to node. Even change to [node.name](http://node.name) won't make the node to start Why is it not startig again after just the [node.name](http://node.name) change.. or how can I see why it can't start ? ---

Most of the time it's caused by a bad yml file. Wrong indentation, space missing... ---
