Amazon EMR uses Hadoop processing combined with several AWS products to do such tasks as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehousing. Documentation is available via [Hackage](http://hackage.haskell.org/package/amazonka-emr) and the [AWS API Reference](http://docs.aws.amazon.com/ElasticMapReduce/latest/API/Welcome.html). ## Contribute For any problems, comments, or feedback please create an issue [here on GitHub](https://github.com/brendanhay/amazonka/issues). > _Note:_ this library is an auto-generated Haskell package.
