Brandon Li updated HDFS-7942:
-----------------------------
Description:
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}
