Changing mapreduce.application.classpath via Ambari doesn't prompt for Hive Restart

When you change mapreduce.application.classpath under Ambari, it requests that you restart MapReduce and Yarn. At that time, you have a stale mapred-site.xml under /etc/hive/conf. Current workaround is to restart the Hive service.
I have verified this by simply changing the mapreduce.application.classpath parameter under Ambari and noticed that hive is not labeled for restart.
