Windows binaries for Hadoop versions

These are built directly from the same git commit used to create the official ASF releases; they are checked out and built on a windows VM which is dedicated purely to testing Hadoop/YARN apps on Windows. It is not a day-to-day used system so is isolated from driveby/email security attacks.

Note that I am a Hadoop committer: I have nothing to gain by creating malicious versions of these binaries. If I wanted to run anything on your systems, I'd be able to add the code into Hadoop itself, or its build process.

I'm moving to gpg -armor signing of binaries; the GPG key used is on the MIT key server

in hadoop-trunk

Check out the git commit ID voted on as the final release of the ASF artifacts.

mvn clean
mvn package -Pdist -Dmaven.javadoc.skip=true -DskipTests

This creates a distribution, with the native binaries under hadoop-dist\target

1. create dir winutils/$VERSION
2. copy bin* to winutils/$VERSION
3. rm stuff you don't want
4. add the rest
5. GPG sign, add .ASC files.
6. commit
7. push
