[jira] [Created] (HADOOP-16081) DistCp: Update "Update and Overwrite" doc

JIRA jira@apache.org
Siyao Meng created HADOOP-16081:

             Summary: DistCp: Update "Update and Overwrite" doc
                 Key: HADOOP-16081
                 URL: https://issues.apache.org/jira/browse/HADOOP-16081
             Project: Hadoop Common
          Issue Type: Task
          Components: documentation, tools/distcp
    Affects Versions: 3.1.1
            Reporter: Siyao Meng
            Assignee: Siyao Meng


In the current doc, it says that -update or -overwrite won't copy the directory hierarchies. i.e. the file structure will be "flattened out" on the destination. But this has been improved already. (Need to find the jira id that made this change.) The dir structure WILL be copied over when -update or -overwrite option is in use.

Now the only caveat for -update or -overwrite option is when we are specifying multiple sources, there shouldn't be files or directories with same relative path.
