Hi All,

I am starting up 3 elasticsearch services to try to utilise the large amount of 
memory my server has (~390GB).

I have just made copy's of the /etc/init.d script and changed them to point to 
their own configuration file. Then ran update-rcd to ensure they run on boot..

I can see the 3 processes running all pointing to there own config files.


Each configuration file has the same cluster name



################################### Cluster ###################################

# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
cluster.name: elasticsearch


However I've given them different Node names.  i.e Node1, Node2 and Node3

#################################### Node #####################################

# Node names are generated dynamically on startup, so you're relieved
# from configuring them manually. You can tie this node to a specific name:
#
node.name: Node1

However when I when I running 'curl localhost:9200/_nodes/process?pretty'  I 
notice they all have the same Node Name.... is that correct? Also does 
everything else look ok?
