> Currently administrator needs to configure both 
> _dfs.data.transfer.protection_ and _hadoop.rpc.protection_ to specify _QOP_ 
> for rpc and data transfer protocols. In some cases, the values for these two 
> properties will be same. In those cases, it may be easier to allow 
> dfs.data.transfer.protection default to hadoop.rpc.protection.
> This also ensures that an admin will get QOP as _Authentication_ if admin  
> does not specify either of those values.
