Description
For deployments that use security. User impersonation (AKA doAs()) is needed for some services (ie Stargate, thriftserver, Oozie, etc). Impersonation definitions are defined in a xml config file and read and cached by the ProxyUsers class. Calling this api will refresh cached information, eliminating the need to restart the master/regionserver whenever the configuration is changed.
Implementation just adds another method to AccessControlService.
