thx for doing this, I'll keep an eye on the builds

one question: which jdk8? Some of the Hadoop builds (example YARN) are cras=
hing the JVM..there's a whole list of jdk8 options, including, for ubuntu h=
osts only, openjdk. Should we switch the jvm for our nightly builds to open=
 jdk 8?

r first Apache Yetus release as well as clean up the jobs to be less hacky.
