----------------------------------------
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.
