Yinghau, Last week you mentioned that you are running your cluster on EC2 that you shut them down instance(s) over the weekend.
QTE Since I shutdown the EC2 instance every night, I thought that using 'master','slave1','slave2' will save typing after the full host name change with reboot. UNQTE Whenever I re-start an instance on Amazon cloud my both internal and external ip addresses for the instance change... ? p.s. Has anyone successfully configured Zookeeper to curb this matter?

I will try using SSH proxy and see how it goes.

But I only have terminal access to the EC2 NN. To run internet browser there will be a lot of more work. the SSH proxy sets up something that appears to be a SOCKs proxy -but which routes to the far end; you set your browser to go through this proxy (foxyproxy is a good firefox plugin here), and then your browser has access to all the machines see http://www.linuxjournal.com/content/use-ssh-create-http-proxy Since my cluster will be shut down at night and weekend. I will prefer to have an IP that does not change. How do you think of using EC2 Elastic IP? not tried that; I have used dyndns.org<http://dyndns.org> to self register an IP address that changes every time you bring up an instance, but whose browser bookmarks can remain fixed -- Regards, Yinghua NOTICE: This e-mail message and any attachments are confidential, subject to copyright and may be privileged.
