> The default nameservice can provide some default properties for the namenode
> protocol. And if we cannot find the path, we will get a location in default
> nameservice. From my side as cluster administrator, we need all files to be
> written in the location from the MountTableEntry. If no responding location,
> some error will return. It is not better to happen some files are written in
> some unknown location. We should provide a specific parameter to enable the
> default nameservice to store files.
