Hi,

I have a weird situation: one of the servers appears twice in the cluster,  
once at port 9300 and the second time on port 9301.  
What can cause this behaviour? Elasticsearch is running only once on that  
machine.

Thanks,  
roxana

Are you sure? I think you'll find another instance running

May be you are just getting two nodes with the same node.name (this can  
happen).

Yes, there were 2 instances running, sorry for the false alarm.
