Hi, I had installed a single node Mapr 5.2 in CentOS 7 VM. The particular VM has 2 users. As far what I understand volume, it can do the permission settings so that user A cannot see data in user B or user B cannot see data in user A. However, I have questions regards to volume as followed:


1. Is volume must be mounted on MapR-FS only? When I create volume, I can only specify path in MapR FS or else it will not recognize and prompt me errors. How about if I want to do some permission settings such as allow user A to view certain Hive tables and user B to view the other Hive tables that user B cannot view?


2. When I set the volume permission using user A (root user) to allow only user B the read/write access to the mounted volume in MCS, both user A and B can access to the mounted volume. Can I limit to only user B can view the files?
