----------------------------------------

             Summary: Clean up argument parsing in mapred CLI
                 Key: MAPREDUCE-6636
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6636
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: client
            Reporter: Robert Kanter


{{org.apache.hadoop.mapreduce.tools.CLI}} manually parses arguments, which has a number of
downsides including (a) requiring strict ordering of arguments by the user and (b) it's hard
for devs to add new arguments.

We should replace all of this with a CLI parsing library like {{org.apache.commons.cli.CommandLineParser}},
which is used in a number of other places already.
