> i would very much like the option of submitting jobs from a workstation
> outside ec2 to a hadoop cluster in ec2. This has been explored here:
> http://www.nabble.com/public-IP-for-datanode-on-EC2-tt19336240.html
> the net result of this is that we can make this work (along with using a
> socks proxy) with a couple of changes in the ec2 scripts:
> a) use public 'hostname' for fs.default.name setting (instead of the private
> hostname being used currently)
> b) mark hadoop.rpc.socket.factory.class.default as final variable in the
> generated hadoop-site.xml (that applies to server side)
> #a has no downside as far as i can tell since public hostnames resolve to
> internal/private IP addresses within ec2 (so traffic is optimally routed).
