[~daisuke.kobayashi] Thanks for working on this. The patch looks good to me.
What's the target version of this patch?

> 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.
