Consequences of setting more restrictive permissions on toplevel MFS dirs.

Are there any sideffects of changing the permissions of the top-level dirs. (eg. /users, /var, /opt, /oozie) in the MFS to being totally inaccessible to non-group or owner users (ie. changing permissions from the default 775 to 770)? 


The reason for wanting to do this is that we are about to set up mapr-client on a server for other users. Once they are able to use the hadoop command from this server, they will have ability to navigate the MFS via hadoop commands. Is it a good idea to have these users not be able to see these toplevel files at all?
