Simple question

Hello everyone,

I'm quite interested in such distributed filesystems but actually I
cannot find this information anywhere: is Hadoop-DFS a POSIX compliant
system ?
Could I mount somehow (Fuse, NFS, or whatever) and use it like that ?

Thanks.

Permissions are a big deal, and are unavoidable at some point, as are
quotas.
We'll get around to implementing these at some point, but they're still in
the requirements phase at best. Input or contributions will be welcome.

Thank you for your answer.

So I guess there is no way to handle users permissions or even quota
using the Hadoop-DFS filesystem.

Too bad, I'm still looking for such a filesystem that would be
fault-tolerand but so far I failed to find something advanced enough
to be usable. If anyone has any hints, feel free to email me (no need
to annoy the list with that since it would probably become off-topic).

Thanks a lot.

Hadoop-DFS is not POSIX compliant.
There exists fuse support for the DFS, see
https://issues.apache.org/jira/browse/HADOOP-4.
There is also work in progress to support the WebDAV protocol. That will
enable WebDAV clients to mount and access the file system.
In both cases it will still not be POSIX compliant.
