>                 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
>            Assignee: Brandon Li

> 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.
