[jira] [Created] (MAPREDUCE-6624) Include TeraChecksum in Hadoop mapreduce examples driver

Albert Chu created MAPREDUCE-6624:
-------------------------------------

             Summary: Include TeraChecksum in Hadoop mapreduce examples driver
                 Key: MAPREDUCE-6624
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6624
             Project: Hadoop Map/Reduce
          Issue Type: Wish
          Components: examples
    Affects Versions: 2.7.1
            Reporter: Albert Chu
            Priority: Minor


In the mapreduce examples driver, you can run TeraGen, TeraSort, and TeraValidate.  To my surprise, TeraChecksum wasn't included in the examples driver.  I think it'd be nice to include.  It can be used to compare the checksum of the input & output.  It's worth noting that TeraValidate calculates the checksum as well.

Patch to be posted shortly.  I tested against 2.7.1 branch but couldn't against master.  I am including patches for both.  Patch also includes TeraChecksum test case addition.
