I created an index with K shards on a single AWS EC2 instance using K  
JVMS. I now want to add more AWS EC2 instances to the mix.

If I clone my original AWS EC2 instance AND data and change the  
gateway configuration to expect 2\*K nodes, and start up K ES servers  
on each AWS instance, will  
the cloned node use the cloned data or will it discard the cloned data  
and copy the cloned data from a primary node when assuming  
responsibility for a shard?

Why are you using K JVMs? Why not one per instance?

> change the gateway configuration to expect 2\*K nodes

no need to change configuration if you only want to add servers.

> will the cloned node use the cloned data

I think it'll use the cloned data, but I'm not sure if its a good idea  
(at least flush before copying the instance).

K JVMs per AWS EC2 instance is a bad idea.

However, I wanted to test AWS clustering without having to start/stop  
multiple instances.

Thx.
