Lin Yiqun commented on HDFS-10234:
----------------------------------
Upload a simple patch from me. I added the log output info for copying and and
creating directories. But it seems there was no place indicated that the file
is deleted in class {{CopyMapper}}. Can this patch satisfied you. If I was
missing something, you can tell me.
> DistCp log output should contain copied and deleted files and directories

> DistCp log output (specified via {{-log}} command line option) currently
> contains only skipped and failed (when failures are ignored via {{-i}}) files.
> It will be more useful if it also contains copied and deleted files and
> created directories.
