> Currently, when GenericOptionsParser encounters an unrecognized option, it stops processing
command-line arguments, and returns the rest to the specific Tool. This forces users to remember
the order of arguments, and leads to errors such as following:
> org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option:
> -Dmapred.reduce.tasks=4
>         at org.apache.commons.cli.Parser.processOption(Parser.java:368)
>         at org.apache.commons.cli.Parser.parse(Parser.java:185)
>         at org.apache.commons.cli.Parser.parse(Parser.java:70)
>         at
> MyTool.run(MyTool.java.java:290)
>         at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
>         at
> MyTool.main(MyTool.java:19)
> In Hadoop-streaming as well, -D parameters should appear before streaming-specific arguments,
such as -mapper, -reducer etc.
> If GenericOptionsParser were to scan the entire command-line, ignoring unrecognized (tool-specific)
options, and returning all unrecognized options back to the tool, this problem would be solved.
