ACLs are a super-set of permissions.
+`-p[rbugpcax]` | Preserve r: replication number b: block size u: user g: group p: permission
c: checksum-type a: ACL x: XAttr | Modification times are not preserved. Also, when `-update`
is specified, status updates will **not** be synchronized unless the file sizes also differ
(i.e. unless the file is re-created). If -pa is specified, DistCp preserves the permissions
also because ACLs are a super-set of permissions.
 `-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.
 `-m <num_maps>` | Maximum number of simultaneous copies | Specify the number of maps
to copy data. Note that more maps may not necessarily improve throughput.
