Question about HDFS

[Prentice Bisbal <pr...@rutgers.edu>]

We had a CDH 4 cluster here that I upgraded to CDH5, where we were using 
HDFS on top of Lustre, set up like you would for NFS, where each Name 
node and  data node is writing it's data to a separate sub directory on 
Lustre. Now that I've upgraded all the node to CDH5, is it possible to 
point the new nodes at the old HDFS directories to retrieve data from 
that CDH4 HDFS filesystem? I used a new location for the location of the 
HDFS dirs on the CDH5 system, so the old HDFS data hasn't been touched.
