> *Problem*
> Currently we run all Hadoop tests in synthetic "single JVM" mode. This way we miss lots
of potential issues. We need to be able to run them in real distributed mode, but on a single
machine.
> *Simplified solution*
> 1) Start N external nodes
> 2) Submit a job to these nodes and validate the result
> We can start with simple TeraGen->TeraSort->TeraValidate scenario. 
> Please look through {{Process}} and {{ProcessBuilder}} classes usages - most probably
we already have all necessary infrastructure to start nodes in external JVM.
