Distinct minicluster services (e.g. NN and JT) overwrite each other's service policies
--------------------------------------------------------------------------------------

                 Key: HADOOP-6951
                 URL: https://issues.apache.org/jira/browse/HADOOP-6951
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
            Reporter: Aaron T. Myers


Because the protocol -> ACL mapping in ServiceAuthorizationManager is static, services
which are run in the same JVM have the potential to clobber the other's service authorization
ACLs whenever ServiceAuthorizationManager.refresh() is called. This causes authorization failures
if one tries to launch a 2NN connected to a minicluster with hadoop.security.authorization
enabled. Seems like each service should have its own instance of a ServiceAuthorizationManager,
instead of using static methods.
