> when we have federation set up, the default file system would become viewfs, 
> trash emptier is going to scan viewfs://namespace/user. However, if we don't 
> have a link in the mounttable.xml (viewfs://namespace/user ---> 
> hdfs://namespace/user), then trash emptier cannot find the user directory. 
> Therefore, we should have namenode use hdfs as its default filesystem
