Andrew Wang updated HDFS-5174:
------------------------------
Description: Right now, DFSAdmin uses an array of different techniques to
do parsing of command line arguments and displaying help text. It'd be better
to unify everything to use a standard library like Commons CLI or JCommander,
which should clean up the file and reduce the amount of custom code we're
carrying. (was: Right now, DFSAdmin uses an array of different techniques to

Summary: Convert DFSAdmin to use a standard library for parsing
arguments (was: Convert DFSAdmin to use Commons CLI for parsing arguments)
Hey Steve, I hadn't heard of JCommander before, but it does look nice. I edited
the JIRA to sound more generic; honestly, choice of library is up to whoever
wants to take this on :)
