-------------------------------------
Assignee: Haibo Chen
> 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
> Assignee: Haibo Chen
>
> {{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.
