> 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).
