private static void updateACLs(final HBaseTestingUtility util, Callable c) throws Exception {
// Get the current mtimes for all access controllers
final Map<AccessController,Long> oldMTimes = getAuthManagerMTimes(util.getHBaseCluster());
// Run the update action
c.call();
// Wait until mtimes for all access controllers have incremented
