Subject [jira] [Commented] (HADOOP-8079) Proposal for enhancements to Hadoop for Windows Server and Windows Azure development and runtime environments
Date Mon, 12 Mar 2012 13:22:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13227506#comment-13227506

Steve Loughran commented on HADOOP-8079:

Another nice feature would be for Win32/64 versions of the native libraries to be available
alongside the Hadoop releases (and an OS/X version too). Integrating this into the main release
process would be tricky, but a Windows VM with optimising 32 and 64 bit compilers could be
used to do a simultaneous release

> 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.
