    Description

      When disctp is triggered to copy a directory to an already existing file, it just shows a "copy failed" error message after 4 attempts without showing any useful error message. This is extremely time consuming on a large cluster and especially when the directory being copied contains several sub-directories.
      Instead, it would be an improvement if distcp could return immediately displaying a useful error message when an user attempts such an operation. (This is an unlikely situation but still a valid test case)
