    Hm. I'd like to merge this since Hadoop 2.x seems like a much more sensible default these days. 
    
    This doesn't change whether Spark works with Hadoop 1.x and doesn't change what builds are released, etc. 
    
    The thing I think it *will* change is what version of Hadoop the Maven artifacts appear to depend on. As we've discussed a lot, this shouldn't matter in theory. Still, a 2.x dependency strikes me as less likely to cause problems since people are much more on 2.x these days.
    
    It will also mean a default "mvn compile" will show some warnings about deprecated Hadoop APIs, but hey.
    
    Any other thoughts on this? I would like to get at least one more confirmation that this seems sensible before I push the button.
