> NFS: support regexp grouping in nfs.exports.allowed.hosts
> ---------------------------------------------------------
>
> Key: HDFS-7942
> URL: https://issues.apache.org/jira/browse/HDFS-7942
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: nfs
> Affects Versions: 2.6.0
> Reporter: Brandon Li
> Assignee: Brandon Li
> Attachments: HDFS-7942.001.patch, HDFS-7942.002.patch

> Thanks, [~yeshavora], for reporting this problem.
> Set regex value in nfs.exports.allowed.hosts property.
> {noformat}
> <property><name>nfs.exports.allowed.hosts</name><value>206.190.52.[26|23]
> rw</value></property>
> {noformat}
> With this value, neither 206.190.52.26 nor 206.190.52.23 can mount nfs and
> act as nfs client. In conclusion, no host can mount nfs with this regex value
> due to access denied error.
> {noformat}
> >$ sudo su - -c "mount -o
> >soft,proto=tcp,vers=3,rsize=1048576,wsize=1048576,nolock 206.190.52.23:/
> >/tmp/tmp_mnt" root
> mount.nfs: access denied by server while mounting 206.190.52.23:/
> {noformat}
