Todd Lipcon created HADOOP-9209:
-----------------------------------

             Summary: Add shell command to dump file checksums
                 Key: HADOOP-9209
                 URL: https://issues.apache.org/jira/browse/HADOOP-9209
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs, tools
    Affects Versions: 3.0.0, 2.0.3-alpha
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


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).
