> The workflow of dynamically changing data volumes on DataNode is
> # Users manually changed {{dfs.datanode.data.dir}} in the configuration file
> # User use command line to notify DN to reload configuration and updates its
> volumes.
> This work adds command line support to notify DN to reload configuration.
