> In large shared deployments of the M/R clusters, it is normal that new users will periodically want to get access to some queues on the M/R framework. Requiring a JT restart for each such change is operationally inconvenient and seems an overkill. There should be a way for updating ACLs with new users without requiring a JT restart.
