Subject [jira] [Created] (HDFS-6456) NFS: NFS server should throw error for invalid entry in dfs.nfs.exports.allowed.hosts
Date Wed, 28 May 2014 18:09:01 GMT
Yesha Vora created HDFS-6456:
--------------------------------

             Summary: NFS: NFS server should throw error for invalid entry in dfs.nfs.exports.allowed.hosts
                 Key: HDFS-6456
                 URL: https://issues.apache.org/jira/browse/HDFS-6456
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: nfs
    Affects Versions: 2.2.0
            Reporter: Yesha Vora


Pass invalid entry in dfs.nfs.exports.allowed.hosts. Use - as separator between hostname and
access permission 

{noformat}
<property><name>dfs.nfs.exports.allowed.hosts</name><value>host1-rw</value></property>
{noformat}

This misconfiguration is not detected by NFS server. It does not print any error message.
The host passed in this configuration is also not able to mount nfs. In conclusion, no node
can mount the nfs with this value. A format check is required for this property. If the value
of this property does not follow the format, an error should be thrown.
