The service-level authorization configuration for the NameNode and JobTracker can be changed without restarting either of the Hadoop master daemons. The cluster administrator can change `$HADOOP_CONF_DIR/hadoop-policy.xml` on the master nodes and instruct the NameNode and JobTracker to reload their respective configurations via the `-refreshServiceAcl` switch to `dfsadmin` and `mradmin` commands respectively.
