----------------------------------------

Hi Tom,

I've now run test-core and test-patch on both HDFS-1399 and MAPREDUCE-2067. Would you mind
taking another look at this?

Thanks a lot,
Aaron

> 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.
