Is Hadoop a extreme transaction processing tool? Can Hadoop be integrated any NoSQL data store?

I would classify Hadoop as a "extreme record processing tool". Hadoop doesn't have transactional semantics which are offered by relational databases. It's really a batch-based system that allows you to work with large data volumes at scale.

HBase would be the canonical example of Hadoop integration with a NoSQL system. There's an article on Oracle's site about Hadoop integration with their NoSQL data store: http://www.oracle.com/technetwork/articles/bigdata/nosql-hadoop-1654158.html
 
Don't get me started about those stupid light bulbs.
