> 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"'.
