----------------------------------

    Attachment: hadoop-9660-branch2_v3.patch
                hadoop-9660-branch1_v3.patch

Thanks for the reviews. Attaching v3 which adds the unit test and fixed IOOBE from Ivan's comments. 

I'll commit this to trunk and hadoop-2. Should we also get this in branch-1-win and hadoop-2.1.0 next rc?

> When parsing parameters to a class implementing Tool, and using ToolRunner, we can pass 
> {code}
> bin/hadoop <tool_class> -Dkey=value 
> {code}
> However, powershell parses the '=' sign itself, and sends it to  java as ["-Dkey", "value"] which breaks GenericOptionsParser. 
> Using "-Dkey=value" or '-Dkey=value' does not fix the problem. The only workaround seems to trick PS by using: 
> '"-Dkey=value"' (single + double quote)
> In cmd, "-Dkey=value" works, but not '"-Dkey=value"'.
