+#### Init ViewFs To Router
+Router supports initializing the ViewFS mount point to the Router. The mapping
directory protocol of ViewFS must be HDFS, and the initializer only supports
one-to-one mapping.
+
+For example, use the following viewfs to configure the initial mount table to
the router.
+
+ <configuration>
+ <property>
+ <name>fs.viewfs.mounttable.ClusterX.link./data</name>
+ <value>hdfs://nn1-clusterx.example.com:8020/data</value>
+ </property>
+ </configuration>
+
+The ViewFS mount table can be initialized to the Router by using the following
command:
+
+ [hdfs]$ $HADOOP_HOME/bin/hdfs dfsrouteradmin -initViewFsToMountTable
ClusterX
