             Summary: Make sure YARN builds against all compatible Giraph versions, warns if none set, works w/new 1.1.0 line
                 Key: GIRAPH-688
                 URL: https://issues.apache.org/jira/browse/GIRAPH-688
             Project: Giraph
          Issue Type: Bug
            Reporter: Eli Reisman
            Assignee: Eli Reisman
            Priority: Minor


This makes the hadoop-yarn branch build again against all compatible Hadoop versions, warns (in a crude but accurate way) what to do if user did not set hadoop.version at the mvn command line...and passes mvn clean verify etc.

I have removed a hardcoded version setting and replaced it with the destined-to-fail warning to allow/force folks to stay on top of which version they will build against (the 2.x Hadoop line is growing quickly!)

The correct way (thanks Eugene!) to build our YARN branch against any compatible Hadoop, as of now, is this:

mvn -Phadoop_yarn -Dhadoop.version=2.0.3-alpha clean install

Where 2.0.3 can be any 2.0.x line, or Hadoop trunk if you like. Consult our POM.XML files to see the various profiles we support for newer Hadoops, and select the hadoop.version you see in your favorite to build, as shown above.

Thats it. Enjoy.
