I was doing my dutiful citizenship work yesterday by building & testing slider against the Hadoop 2.6.4 RC0; it wouldn't build at first as it couldn't find the hadoop-azure artifact —the one that only came with Hadoop 2.7
I've tweaked the build to leave out the dependency unless you explicitly go -Pazure on the command line https://issues.apache.org/jira/browse/SLIDER-1085 1. If you are targeting azure, use the profile. 2. I'm adding this to the release.xml build file so it happens automatically on a release 3. We're going to have to decide when to move on to Hadoop 2.7.1 as a minimum. Currently there's no real cost to supporting Hadoop 2.6.x on Java 7 only; only one little bit of reflection needed at application launch to set up the rolling logs properly. Once Hadoop 2.8 comes out, it'll complicate the test matrix more: three versions of Hadoop to test against. I think I'd like to switch to 2.7.x as a minimum then, as it will leave us with the current setup: two Hadoop versions, two java versions, two OSs (windows, Linux) and two security options (off, on); enough that you can test everything with two separate clusters; Windows + Java 8 + insecure, and Linux + java 7 + kerberos. What do people think? -Steve
