@vanzin @srowen thanks your notice and commentï¼ I means that if make
Yarn Cluster know about the federated HDFS service, We should distribute the
mount table XML in the cluster and by restart Yarn Cluster bring into effect.
under this circumstancesï¼if We change the mount table or HA settingsï¼we
should restart Yarn Cluster again. In additionï¼I dont think this is a
bugï¼but its a feature . if it is possibleï¼We can make Yarn no need to know
about the federated HDFS service like MR & Hive
