Improve CommandFormat
---------------------
Key: HADOOP-7180
URL: https://issues.apache.org/jira/browse/HADOOP-7180
Project: Hadoop Common
Issue Type: Improvement
Reporter: Daryn Sharp
Fix For: 0.22.0
CommandFormat currently takes an array and offset for parsing and returns a
list of arguments. It'd be much more convenient to have it process a list too.
It would also be nice to differentiate between too few and too many args
instead of the generic "Illegal number of arguments". Finally, CommandFormat
is completely devoid of tests.
