Description

This is problematic, if the command hangs for e.g, we don't get any logs to indicate where its hanging at.. Better approach is to use something like Piped{Input|Oupput}Stream to implement a thread that can keep printing stdout and stderr as the command runs..

Relevant classes : ITTestHoodieDemo/ ITTTestBase
