[Lustre-discuss] Understanding lustre setup ..

[linux freaker]

Hello,

I have been reading
http://wiki.lustre.org/images/1/1b/Hadoop_wp_v0.4.2.pdf for setting up
Hadoop over lustre.
Generally in hadoop setup, we have 1 Namenode and various number of datanodes.
If I want to setup the same keeping Lustre as backend, in the document
it is mentioned that:

".............Our experiments run on cluster with 8 nodes in total,
one is mds/namenode, the rest are
OSS/DataNode".

I wonder where does the Lustre Client fit here?

For Hadoop to work , we mention filesystem parameter esp /lustre here.
We dont have /lustre on OSS.
How is it possible?
