Doubt: Regarding running Hadoop on a cluster with shared disk.

[Udaya Lakshmi]

Hi,
   I have an account on a cluster which is having a file system similar to
NFS. If I create a file on one machine it is being shown on all the machines
in the cluster. But hadoop will work on a cluster of machines, where in ,
each machine has a disk of its own. Can someone please help me use hadoop on
my cluster.
Thanks,
Udaya.
