Ted Yu commented on HBASE-14169:
--------------------------------

Normally there is a space between double slash and the comment itself.
{code}
953	      //refresh proxy users on startup, this is for
{code}
The method is called refreshSuperUserGroupsConfiguration() while comment mentions 'proxy users'.
Better use the same term.

{code}
954	      //when backup master become an active master
{code}
'become' -> 'becomes'

> 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.
