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.
