Assuming that the following is your initial questions: *"My question here is how benefits YARN architecture give me in tems of analysis that my Microsoft, Netezza of Tableau products are not giving me. I am just trying to understand value of introducing Hadoop in my Architecture in terms of Analysis apart from data replication."*
YARN is not 'data storage' (hence replication does not matter her) or even only just 'Analytics'. It is a framework that allows you to write or implement applications which are based on distributed architecture. In pre-Yarn world it was Map/Reduce but in YARN now you can not only work on Map/Reduce based applications but any other distributed paradigm. YARN helps you in taking care of lots of boiler-plate plus advance plumbing and infrastructure concerns usually encountered with parallel distributed applications. I have not worked in Netezza but from what I understand, Yarn and the distributed applications build on it are not just for Analytics. They can be any application which wants to leverage a highly distributed and parallel architecture and design. So basically YARN is giving you a environment where you can implement applications using custom (or the popular Map/Reduce) paradigm to build parallel an distributed applications. As YARN is open source, so you have much more control over it. You can get the code and modify it to your own needs which I presume is nota available or possible in Netezza. I didn't get what application you are mentioning when you said 'Microsoft'. Others, experts can chime in.
