Masatake Iwasaki commented on HDFS-9048:
----------------------------------------
{{namenode_address}} or {{namenode_host}} should be fine.
> DistCp documentation is out-of-dated

>
> There are a couple issues with the current distcp document:
> * It recommends hftp / hsftp filesystem to copy data between different hadoop
> version. hftp / hsftp have been deprecated in the flavor of webhdfs.
> * If the users are copying between Hadoop 2.x they can use the hdfs protocol
> directly for better performance.
