NFS Gateway readonly issue
Hello,
we are experiencing a strange issue with our Hadoop cluster implementing NFS Gateway.
We exported our distributed filesystem with the following configuration (Managed by Cloudera Manager over CDH 5.0.1):
<property>
<name>dfs.nfs.exports.allowed.hosts</name>
<value>192.168.0.153 ro</value>
</property>
As you can see, we expect the exported FS to be read-only, but in fact we are able to delete files and folders stored on it (where the user has the correct permissions), from the client machine that mounted the FS.
Other writing operations are correctly blocked.
Hadoop Version in use: 2.3.0+cdh5.0.1+567
Bye.

Hello,
I was able to reproduce the issue on latest hadoop trunk. Though for me, I
could only delete files, deleting directories were correctly blocked. I
have opened https://issues.apache.org/jira/browse/HDFS-6703 to further
track the issue. Thanks for reporting!
