Hide MapR-DB tables from FS APIs

Idea created by MichaelSegel on Sep 1, 2017

    Because the MapR-FS is really a 'blob space' manager which supports multiple APIs, it makes sense to hide the tablets and MapR-DB files and directories from external access.


    This would simplify the understanding of MapR-DB and would reduce the potential for external access attempts.


    It would also make it a little bit more secure because of reducing the potential access points.
