Yesha Vora created HDFS-6458:
--------------------------------

             Summary: NFS: stale NFS file handle Error for previous mount point
                 Key: HDFS-6458
                 URL: https://issues.apache.org/jira/browse/HDFS-6458
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: nfs
    Affects Versions: 2.2.0
            Reporter: Yesha Vora


Steps to reproduce:
1) Set dfs.nfs.exports.allowed.hosts = <Gateway> rw
2) mount nfs on <Gateway>
3) Set dfs.nfs.exports.allowed.hosts = <Datanode> rw
4) mount nfs on <Datanode>

Try to access NFS mount point at Gateway. Can't access mount point from Gateway. 
{noformat}
bash: ls /tmp/tmp_mnt 
ls: cannot access /tmp/tmp_mnt: Stale NFS file handle
{noformat}

Expected: Mount_point from previous config should be accessible if it is not unmounted before config change.
