Fix option parsing in CommandFormat
-----------------------------------
Key: HADOOP-7341
URL: https://issues.apache.org/jira/browse/HADOOP-7341
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.23.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
CommandFormat currently allows options in any location within the args. This
is not the intended behavior for FsShell commands. Prior to the redesign, the
commands used to expect option processing to stop at the first non-option.
CommandFormat was an existing class prior the redesign, but it was only used by
"count" to find the -q flag. All commands were converted to using this class,
thus inherited the unintended behavior.
