Kihwal Lee commented on HADOOP-9209:
------------------------------------
bq. The failed QA Comment was from a mistaken patch that was uploaded to this
JIRA.
The pre-commit ran against a patch that had something extra, but the failure
was not caused by the patch. The audit was about CHANGES.branch-trunk-win.txt
not having the apache license header. Test failure is a known issue after the
windows branch merge.

> Occasionally while working with tools like distcp, or debugging certain
> issues, it's useful to be able to quickly see the checksum of a file. We
> currently have the APIs to efficiently calculate a checksum, but we don't
> expose it to users. This JIRA is to add a "fs -checksum" command which dumps
> the checksum information for the specified file(s).
