Eric Newton commented on ACCUMULO-745:
--------------------------------------

Actually, it seems to me that there are better argument parsing libraries.  JCommander looks pretty nice  and has an apache license.

> In a few utilities, the command-line parsing is pretty lazy.  There's no usage, just an NPE if you don't provide all the magic options on the command-line.  In particular, Initialize doesn't use an off-the-shelf library for command-line parsing, and it really should.
> See ACCUMULO-744.
> In addition, many command-line utilities can and should be able to read accumulo-site.xml, and do not need to provide username/password/instance/zookeeper information by default.
