This is the Amazon Elastic MapReduce API Reference. This section describes who should read this guide, how the guide is organized, and other resources related to this web service.
Amazon Elastic MapReduce, Amazon Elastic Compute Cloud, and Amazon Simple Storage Service are sometimes referred to within this guide as "Elastic MapReduce," "EC2," and "Amazon S3," respectively. All copyrights and legal protections still apply.
This reference is for developers and for the community of researchers and data analysts that need to process vast amounts of data efficiently and cost-effectively.
Elastic MapReduce offers a console, a command line interface, and an API. Each interface requires a slightly different set of skills. The console and command line interface let you execute Elastic MapReduce functionality without having to write full applications. Both of these interfaces, however, require you to write your own mapper and reducer executables in the programming language of your choice.
Of the three interfaces, the API requires the greatest programming skills and knowledge of Hadoop. Even though Elastic MapReduce hides a lot of the Hadoop configuration details, knowing the basics of Hadoop is important.
Developers using the API should be familiar with the following:
XML (for an overview, go to the W3 Schools XML Tutorial )
Basic understanding of web services (for an overview, go to the W3 Schools Web Services Tutorial )
A programming language for writing mapper and reducer executables and for consuming Elastic MapReduce responses
Hadoop (for more information, go to http://hadoop.apache.org/core/)
Familiarity with EC2 and Amazon S3 (for more information, see the Amazon Elastic Compute Cloud Developer Guide and the Amazon Simple Storage Service Developer Guide, respectively)
