All Known Implementing Classes:

KerberosAuthorizor, ZKAuthorizor
```
public interface Authorizor
```
This interface is used for the system which will be used for getting a users Authorizations. If the implementation does not support configuration through Accumulo, it should throw an AccumuloSecurityException with the error code UNSUPPORTED_OPERATION
