Hadoop cluster running in cloudstack

[David Ortiz]

Hello,
    Has anyone tried running a hadoop cluster in a cloudstack environment?  I 
have set one up, but I am finding that I am having some IO contention between 
slave nodes on each host since they all share one local storage pool.  As I 
understand it, there is not currently a method for using multiple local storage 
pools with VMs through cloudstack.  Has anyone found a workaround for this by 
any chance?
Thanks,     David Ortiz
