> 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.
