Answer 1

I think you will find the following article very usefull to your thoughts.

It’s important to divide the techniques of data warehousing from the implementation. Hadoop (and the advent of NoSQL databases) will auger the demise of data warehousing appliances and the “traditional” single database implementation of a data warehouse.  
It is safe to say that traditional, single server relational databases or database appliances are not the future of big data or data warehouses.
On the other hand, the techniques of data warehousing to include Extract-Transform-and-Load (ETL), dimensional modeling and business intelligence will be adapted to the new Hadoop/NoSQL environments.
