Subject [jira] [Commented] (HDFS-4947) Add NFS server export table to control export by hostname or IP range
Date Fri, 02 Aug 2013 20:59:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13728109#comment-13728109

Brandon Li commented on HDFS-4947:
----------------------------------

{quote}...where you would run into multiple hostnames mapping to a single IP is if you had
an entry in /etc/hosts, and then also a DNS server that had some entry.{quote}
Usually(as the default action) name lookup stops when it finds a match with one resource(file/dns/nis),
and then returns the result to the application. (http://linux.die.net/man/5/nsswitch.conf)

> 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.
