+1 Java has done the bulk of the work in making Hadoop multi-platform. Windows specific code is a tiny percentage of the code. Jeninks support for windows is going help us keep the platform portable going forward. I expect that the vast majority of new commits have no problems. I propose that we start by fixing problems that Jenkins raises but not block new commits for too long if the author does not have a windows box or if a volunteer does not step up.
