| `-i` | Ignore failures | As explained in the Appendix, this option will keep
more accurate statistics about the copy than the default case. It also
preserves logs from failed copies, which can be valuable for debugging.
Finally, a failing map will not cause the job to fail before all splits are
attempted. |
| `-log <logdir>` | Write logs to \<logdir\> | DistCp keeps logs of each file
it attempts to copy as map output. If a map fails, the log output will not be
retained if it is re-executed. |
| `-v` | Log additional info (path, size) in the SKIP/COPY log | This option
can only be used with -log option. |
