Eli Collins commented on HDFS-3000:
-----------------------------------
On one hand quotas are not HDFS-specific, so fine moving them out of
DistributedFileSystem. The quota interface isn't entirely generic, eg I'm not
sure other file systems would combine the namespace and diskspace values in one
API, but I suspect it's reasonably generic enough to be useful by another FS.
On the other FileSystem, nor FileContext which would also need this, doesn't
currently have an administrative-level interface (which quotas are). Would it
be better instead to have a new public class for administrative-level APIs that
is public / maintained? Eg in the same way we have haadmin and dfshaadmin,
have both a generic and hdfs-specific dfs admin classes, and make the new one
generic and public?
