Re: Defining Hadoop Compatibility -revisiting-
As a specific example of how these are important, over in Mahout-land we
have been wrestling with determining just what it means to have dependencies
in the lib directory inside a jar.  This isn't documented, behaves
differently in different versions of Hadoop and means that some Mahout
programs work sometimes, but fail in high-profile locations like Twitter.
