> Key: HBASE-20357

> Components: security
> Reporter: Pankaj Kumar

> *Background:*
> Currently HBase ACLs can be retrieved based on the namespace or table name
> only. There is no direct API available to retrieve the permissions based on
> the namespace, table name, column family and column qualifier for specific
> user.
> Client has to write application logic in multiple steps to retrieve ACLs
> based on table name, column name and column qualifier for specific user.
> HBase should enhance AccessControlClient APIs to simplyfy this.
> *AccessControlClient API should be extended with following APIs,*
> # To retrieve permissions based on the namespace, table name, column family
> and column qualifier for specific user.
> Permissions can be retrieved based on the following inputs,
> - Namespace/Table (already available)
> - Namespace/Table + UserName
> - Table + CF
> - Table + CF + UserName
> - Table + CF + CQ
> - Table + CF + CQ + UserName
> Scope of retrieving permission will be as follows,
> - Same as existing
> 2. To validate whether a user is allowed to perform specified
> operations on a particular table, will be useful to check user privilege
> instead of getting ACD during client
> operation.
> User validation can be performed based on following inputs,
> - Table + CF + CQ + UserName + Actions
> Scope of validating user privilege,
> User can perform self check without any special privilege
> but ADMIN privilege will be required to perform check for other users.
> For example, suppose there are two users "userA" &
> "userB" then there can be below scenarios,
> - when userA want to check whether userA have
> privilege to perform mentioned actions
> > userA don't need ADMIN privilege, as it's a
> self query.
> - when userA want to check whether userB have
> privilege to perform mentioned actions,
> > userA must have ADMIN or superuser
> privilege, as it's trying to query for other user.
