Brandon Li created HDFS-7942:
--------------------------------
Summary: NFS: regex value of nfs.exports.allowed.hosts is not
working as expected
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
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
