Suman Sehgal commented on HADOOP-3887:
--------------------------------------
Although the description is there in distcp.pdf but this information is not being displayed by online help (on running "hadoop distcp -help" command).

> "hadoop distcp --help" command gives help regarding the execution of the distcp command but it doesn't give the details about copying data between different versions of Hadoop.
> The example displayed by the help documentation is :
> hadoop distcp -p -update "hdfs://A:8020/user/foo/bar" "hdfs://B:8020/user/foo/baz"
> while copying between different versions, distcp uses hftp protocol instead of hdfs for source path.
