What I think we should allow is to put /a/b in the mount table, even thought it's not a top-level
directory.

so your actual proposal is:
1. users can only mount the directories in the export table, and
2. the directories in the export table should not have ancestor-children relationship (not
nested)

Then we will have the tricky problem as I mentioned above: if /a and /a/b are both in export
table, "export /a is read-only but /a/b is read-write, when user traverse from /a to /a/b,
it's tricky to decide which access the user should have"

> 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.
