how is separation of users done in hbase so that one user does not see the tables created by the other user ?
we are using Ranger and Kerberos.
In ranger you have Capability to provide access to tables and/or namespace via user ID or groups. Take a look at similar question which was answered by me here:
is namespace in hbase kind of schmea in RDMS ? so each user can have his/her own space where he/she creates the tables?
I read your link and its not answering the question weather Ranger can implement security at the namespace level ?
