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 path.
