Andrew Purtell updated HBASE-7123:
----------------------------------

    Description: 
The authorize(), permissionGranted(), and requirePermission() methods in 
AccessController have organically grown as both the HBase client API and the 
AccessController itself have evolved, and now have several problems:

- Code duplication (minor)

- Unused variants (minor)

- Signatures optimized for checking certain operations that have a familyMap. 
Unfortunately different operations have different ideas of what type a 
familyMap should be. This leads to runtime type checking and the need to 
convert one family map to another (e.g. {{Map<byte[], 
NavigableMap<byte[],Object>>}} to {{Map<byte[], Set<byte[]>>}} (That kind of 
conversion code in a hot path hurts to look at.) There are too many Java 
collection type combinations floating around. Some of this should be approached 
at the client API level too, for example with HBASE-7114.

- Only one Permission.Action can be checked at a time. We should really convert 
these into a bitmap if multiple actions need checking and pass that around 
instead.
