> HDFS federation support multiple namenodes horizontally scales the file system namespace.
As the amount of data grows, using a single group of namenodes to manage a single directory,
namenode still achieves performance bottlenecks. In order to reduce the pressure of namenode,
we can split out the secondary directory, and manager it by a new namenode. This is  transparent
for users. 
> For example, nn1 only manager the /user directory, when nn1 achieve performance bottlenecks,
we can split out /user/hive directory, and ues nn2 to manager it.
> That means core-site.xml should support as follows configuration.
>    <property>
>        <name>fs.viewfs.mounttable.nsX.link./user</name>
>        <value>hdfs://nn1:8020/user</value>
>     </property>
>     <property>
>        <name>fs.viewfs.mounttable.nsX.link./user/hive</name>
>        <value>hdfs://nn2:8020/user/hive</value>
>     </property>
