Authorizor (Server Base 1.7.0 API)

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

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`changeAuthorizations(String user, Authorizations authorizations)` Used to change the authorizations for the user
`void`	`dropUser(String user)` Deletes a user
`Authorizations`	`getCachedUserAuthorizations(String user)` Used to get the authorizations for the user
`void`	`initialize(String instanceId, boolean initialize)` Sets up the authorizor for a new instance of Accumulo
`void`	`initializeSecurity(TCredentials credentials, String rootuser)` Used to initialize security for the root user
`void`	`initUser(String user)` Initializes a new user
`boolean`	`isValidAuthorizations(String user, List<ByteBuffer> list)` Used to check if a user has valid auths.
`boolean`	`validSecurityHandlers(Authenticator auth, PermissionHandler pm)` Used to validate that the Authorizor, Authenticator, and permission handler can coexist
