Brandon Li commented on HDFS-5523:
----------------------------------
Yes. We should not always export "/" as one of the exports (though that's what
we currently have now.)
We can just allow exporting "/" along with other sub-dirctories. The
administrator will decide when/whether to export it and which host should have
the access.

> Key: HDFS-5523
> URL: https://issues.apache.org/jira/browse/HDFS-5523
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: nfs
> Reporter: Brandon Li
>
> Currently, the HDFS NFS Gateway only supports configuring a single
> subdirectory export via the {{dfs.nfs3.export.point}} configuration setting.
> Supporting multiple subdirectory exports can make data and security
> management easier when using the HDFS NFS Gateway.
