Subject [jira] [Commented] (HDFS-4947) Add NFS server export table to control export by hostname or IP range
Date Fri, 02 Aug 2013 21:19:49 GMT

Colin Patrick McCabe commented on HDFS-4947:
--------------------------------------------

OK.  Let's file a future improvement JIRA about the multiple hostnames issue, then.  That
way people will at least be aware of the issue, even if we don't get to it for a while.

> This jira adds NFS server export table (hostname or IP range) to control export. Specifically,
it
> 1. adds two new classes AccessPrivilege and ClientHostsMatcher for loading and checking
the mapping between client hosts and their access privileges. These two classes are directly
copied from Brock Noland's NFS4 implementation.
> 2. adds the access check (based on the export) to NFS3 procedures.
