Chapter 19. Managing Hadoop Compatible Storage


Hadoop Compatible Storage is a technology preview feature. Technology Preview features are not fully supported under Red Hat subscription level agreements (SLAs), may not be functionally complete, and are not intended for production use. However, these features provide early access to upcoming product innovations, enabling customers to test functionality and provide feedback during the development process. As Red Hat considers making future iterations of Technology Preview features generally available, we will provide commercially reasonable efforts to resolve any reported issues that customers experience when using these features.
Red Hat Storage provides compatibility for Apache Hadoop and it uses the standard file system APIs available in Hadoop to provide a new storage option for Hadoop deployments. Existing MapReduce based applications can use Red Hat Storage seamlessly. This new functionality opens up data within Hadoop deployments to any file-based or object-based application.


When you install Red Hat Storage 2.0, Hadoop Compatible Storage is automatically installed, by default.
