Sanjay Radia commented on HADOOP-8079:
--------------------------------------
@Eli>Why not do this trunk first like we do with other new features? branch-1
is the sustaining branch.
Branch 1-win is just being used as a proof of concept for the patches. The
trunk patches are expected to be provided and checked into trunk before this
jira is completed.

> 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.
> Your feedback solicited,
