[jira] Updated: (HBASE-3025) Coprocessor based simple access control

     [ https://issues.apache.org/jira/browse/HBASE-3025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Purtell updated HBASE-3025:
----------------------------------

        Summary: Coprocessor based simple access control  (was: Coprocessor based RBAC policy engine)
    Description: 
Thanks for the clarification Jeff which reminds me to edit this issue.

Goals of this issue

# Client access to HBase is authenticated
# User data is private unless access has been granted
# Access to data can be granted at a table or per column family basis. 

Non-Goals of this issue

The following items will be left out of the initial implementation for simplicity:

# Row-level or per value (cell) This would require broader changes for storing the ACLs inline with rows. It's still a future goal, but would slow down the initial implementation considerably.
# Push down of file ownership to HDFS While table ownership seems like a useful construct to start with (at least to lay the groundwork for future changes), making HBase act as table owners when interacting with HDFS would require more changes. In additional, while HDFS file ownership would make applying quotas easy, and possibly make bulk imports more straightforward, it's not clean it would offer a more secure setup. We'll leave this to evaluate in a later phase.
# HBase managed "roles" as collections of permissions We will not model "roles" internally in HBase to begin with. We will instead allow group names to be granted permissions, which will allow some external modeling of roles via group memberships. Groups will be created and manipulated externally to HBase. 

While the assignment of permissions to roles and roles to users (or other roles) allows a great deal of flexibility in security policy, it would add complexity to the initial implementation. 

After the initial implementation, which will appear on this issue, we will evaluate the addition of group definitions internal to HBase in a new JIRA. In this scheme, administrators could assign permissions specifying HDFS groups, and additionally HBase groups. HBase groups would be created and manipulated internally to HBase, and would appear distinct from HDFS groups via some syntactic sugar. HBase group definitions will be allowed to reference other HBase group definitions.
