Amen! Finally someone talking sense. Apart from being a hype, Hadoop is also a wet dream for VCs that want to have "exposure" to "big data". Hadoop is a solution for cases where you have multiple petabytes of data, with query's that need to touch a significant portion of your data. Roughly speaking in this case your execution time will scale with the number of nodes in your cluster. Classic example is creating the inverted word list for a search engine. For most other use cases, including all cases where you can index your data, you do not need Hadoop.
