This JIRA is intended to capture discussion around proposed work to enhance Apache Hadoop to run well on Windows. Apache Hadoop has worked on Microsoft Windows since its inception, but Windows support has never been a priority. Currently Windows works as a development and testing platform for Hadoop, but Hadoop is not natively integrated, full-featured or performance and scalability tuned for Windows Server or Windows Azure. We would like to change this and engage in a dialog with the broader community on the architectural design points for making Windows (enterprise and cloud) an excellent runtime and deployment environment for Hadoop.
The Isotope team at Microsoft (names below) has developed an Apache Hadoop 1.0 patch set that addresses these performance, integration and feature gaps, allowing Apache Hadoop to be used with Azure and Windows Server without recourse to virtualization technologies such as Cygwin. We have significant interest in the deployment of Hadoop across many multi-tenant, PaaS and IaaS environments - which bring their own unique requirements.
Microsoft has recently completed a CCLA with Apache and would like to contribute these enhancements back to the Apache Hadoop community.
In the interest of improving Apache Hadoop so that it runs more smoothly on all platforms, including Windows, we propose first contributing this work to the Apache community by attaching it to this JIRA. From there we would like to work with the community to refine the patch set until it is ready to be merged into the Apache trunk.
