Hi Lance,

It's not hard to create the cluster. We are using Xen over Debian Lenny.

We're yet to release our SAAS product in production.

So, We've not load tested it yet.

What were your decision factors in choosing HD over other File Systems?

Our research states that MogileFS is more scalable and good for small files..while HDFS is good for large files.

Regards
Rajan

Hi rajan,

We currently run a 10 hadoop cluster on 3 vmware hosts and I want to create a bigger cluster on a xen cluster of servers. so I was just wanting to find out how easy it is. Our HD cluster maxes out the vmware CPUs for about 4 Hours a day doing our analysis.

So I think your answer says it all for me. It is possible so we should test.

Thanks

Lance

We are working on MogileFS cloud storage over Xen!

We're going to store documents of small size ~1 MB.

What is your business case?

Hi all,

Has anyone created a Xen cluster to run a hadoop vm cluster?

I would be interested in how it performs

Thanks

Lance
