Reg. Hadoop version & RAID

Hi,

I have a quick question w.r.t using the raid contrib in Hadoop map-reduce.

I believe that the initial implementation of raid supported only XOR
encoding but the latest implementation does support Reed-Solomon (RS)
encoding as well.
I was wondering whether or not I could run raid (with RS encoding) in
Hadoop version 0.20.203.0?
If not, what version should I be using?

Appreciate your help.

Regards,
