Subject [jira] [Created] (HDFS-7942) NFS: regex value of nfs.exports.allowed.hosts is not working as expected
Date Tue, 17 Mar 2015 17:55:38 GMT
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
mount.nfs: access denied by server while mounting 206.190.52.23:/
{noformat}
