Spark requires Hadoop to run, so this whole Spark vs Hadoop debate makes no sense whatsoever.
There is a place for arguing how effective Map/Reduce is, but it's been known for years that M/R is not the only, nor best general purpose algorithm for solving all problems. More and more tools these days do not use M/R, Spark including, and Spark certainly is no the first tool to provide an alternative to M/R. AFAIK Google has abandoned M/R years ago.
I just don't understand this constant boasting about Spark, it seems very suspicious to me.
