Description

When parsing parameters to a class implementing Tool, and using ToolRunner, we can pass

bin/hadoop <tool_class> -Dkey=value 

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"'.
