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 won't make the node to start
Why is it not startig again after just the node.name change.. or how can I see why it can't start ?
