This command gives me:
{
"ok" : true,
"cluster_name" : "workshop",
"nodes" : {
"tpgOUNUcTZ2geUXdPk38rA" : {
"name" : "Trapper",
"transport_address" : "inet[/192.168.0.15:9300]",
"hostname" : "MacBook-Air-de-David.local",
"version" : "0.90.6",
"http_address" : "inet[/192.168.0.15:9200]",
"network" : {
"refresh_interval" : 5000,
"primary_interface" : {
"address" : "192.168.0.15",
"name" : "en0",
"mac_address" : "00:88:65:38:10:D6"
}
}
}
}
}
Actually transport_address and http_address are derived from:
network.bind_host: 192.168.0.1
network.publish_host: 192.168.0.1
Or this one set both values (which really often the case):
network.host: 192.168.0.1
About the data directory, as soon as you start a node, you should see at least a clustername/nodes/0/_state where clustername is your actual cluster name (default to elasticsearch).
If you don't see it, I think that you are modifying an elasticsearch.yml file which is not used by your distribution.
Note that you can run elasticsearch using:
bin/elasticsearch -Des.path.conf=/yourdir/elasticsearch.yml

Thanks for the reply. 
curl -XGET 'http://localhost:9200/_nodes/network?pretty' does not return the value of network.publish_host
Or is it called something else in the output?
Also, thanks to the hint provided by the curl command, I found http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html#_nodes_statistics Which helped me confirm that elasticsearch is pointed at the data directory I wanted it to point at. Nothing had appeared in that dir, but this confirms it's just because no data has been sent to this node.

According to the /etc/elasticsearch/elasticsearch.yml config file, Elasticsearch sets a lot of default settings automatically. For example:
Set the address other nodes will use to communicate with this node. If not
set, it is automatically derived. It must point to an actual IP address.
network.publish_host: 192.168.0.1
Is there a way I can get a list of all the configuration values that Elasticsearch is currently running with? So I could see what Elasticsearch automatically derived for "network.publish_host" and other settings.
Look at logs when the server starts is the simplest way.
Or curl -XGET 'http://localhost:9200/_nodes/network?pretty'
Second, if I set up two VM's to use the same cluster via the "cluster.name" setting, they should automatically find each other, right? So I would see them all listed when I run:
curl -XGET 'http://localhost:9200/_cluster/nodes?pretty=true'
Yes
Finally, if I set "path.data" to something, all data should be stored in that location. Not in the default (apparently) /var/lib/elasticsearch. Right?
Yes
Thanks! Apologies if these seem like obvious questions. I have googled, and read the manual looking for answers. I just wasn't able to find the answers, or didn't understand them when I found them...
