Hi Eran,
mapreduce has to store its data on HDFS file system.
More specifically, it needs read/write access to a shared filesystem. If
you are brave enough you can use NFS, too, or any other type of
filesystem that can be mounted locally on each node (e.g. a NetApp).
But if you want to separate the two groups of servers, you could build
two separate HDFS filesystems. To separate the two setups, you will need
to make sure there is no cross communication between the two parts,
You can run two separate clusters even on the same set of machines, just
configure them to use different ports AND different local paths.
