Aaron T. Myers commented on HDFS-6056:
--------------------------------------

bq. Since nfs is in another project, do we still want to move all the 
configuration keys to hadoop-common and hdfs? Maybe in this jira we can first 
make the conf names more consistent and unified, and consider the moving part 
in a separate jira?

Higher level question here - why is any of this code in Common? It's all to 
support HDFS NFS access, so I don't really see how this could be used by 
YARN/MR, or independently of HDFS. Given that, my suggestion would be to move 
all the NFS-related code into the hadoop-hdfs-nfs project, and put all the 
relevant configs there.

Having several of the configs in Common (and therefore with different prefixes 
than the rest of the configs) only seems like it will cause user confusion, and 
not really serve to help anything, given the above.
