> The mapreduce jobs which are run by streaming and demo oozie examples fails with following error:
> Caused by: java.io.IOException: Cannot run program "/bin/cat": CreateProcess error=2, The system cannot find the file specified
> Both have <streaming><mapper>/bin/cat</mapper><reducer>/usr/bin/wc</reducer></streaming> parameters in their workflow.xml. To fix this issue it's needed to have another mapper and reducer programms for Windows. As appropriate analogs on Windows can be "powershell -command "$input | Write-Host"" for mapper and "powershell -command "$input | Measure-Object -Word -Line -Character"" so it's not needed to rewrite any supporting Java code for this examples.
> That's why separated job.properties for Windows and Linux versions were created. Both contains additional parameters "streamingMapper" and "streamingReducer" whose values are commands for OS-specific mapper and reducer.
