    Description

      Add an optional RetriableFileFastCopyCommand to Distcp to support copying a contiguous file from one namespace to another via FastCopy.

      RetriableFileFastCopyCommand will be a subClass of RetriableFileCopyCommand. If the files to be copied does not meet the conditions of FastCopy, it will automatically call the super method to copy the files.

       

      Tips: Current task only supports copy the contiguous file.
