Subject [jira] Created: (HADOOP-3887) Distcp help needs to be more elaborated.

Distcp help needs to be more elaborated.

                 Key: HADOOP-3887
                 URL: https://issues.apache.org/jira/browse/HADOOP-3887
             Project: Hadoop Core
          Issue Type: Bug
          Components: documentation
    Affects Versions: 0.18.0
            Reporter: Suman Sehgal
            Priority: Minor

"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
