Description

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.
