Does wordcount support multiple pairs of inputs/outputs.
{quote}
No, it does not. I retained old code, which was wrong. run method supports only 2 arguments (input path, output path). Correcting this.

Also, the conf object created using the -Dparams is completely ignored. That seems wrong.

Thanks for pointing this out. Fixed. conf is now passed into run method.
