Subject Re: ASF OS X Build Infrastructure
Date Thu, 19 May 2016 17:08:47 GMT
Allen, thank you for doing this.

Regarding lack of personal access to anything but Linux, I'll take this as
an opportunity to remind everyone that ASF committers (not just limited to
Hadoop committers) are entitled to a free MSDN license, which can get you
a Windows VM for validating Windows issues and any patches that touch
cross-platform concerns, like the native code.  Contributors who are not
committers still might struggle to get access to Windows, but all of us
reviewing and committing patches do have access.

It has long been on my TODO list to set up similar Jenkins jobs for
Windows, but it keeps slipping.  I'll try once again to bump up priority.
