There is no single "NoSQL" model, unlike the relational model for SQL databases, so each NoSQL database has different features and may be based on a different approach to modelling/storing/processing your data, and each model will be suitable for different purposes. I can strongly recommend the book "Seven Databases In Seven Weeks" as a way to get a quick introduction to a range of NoSQL databases (and the relational DB PostgreSQL):

Redis, Neo4J, CouchDB, MongoDB, HBase, Riak, and Postgres: with each database, you’ll tackle a real-world data problem that highlights the concepts and features that make it shine. You’ll explore the five data models employed by these databases: relational, key/value, columnar, document, and graph. See which kinds of problems are best suited to each, and when to use them.


As you've already worked with Hadoop, you know more about HBase than I do, but the MongoDB website has plenty of information about MongoDB's approach to data to help you compare and contrast these two NoSQL databases.
