Hey Daniel, welcome to the shady world of shading maven dependencies (and Hadoop not shading its super old guava version ;) ). I'll have a look at your branch. I think Aljoscha added the guava dependency for the test scope of the hadoop1 profile.
He made this change when he moved the HadoopInputFormat support into the "flink-java" package. It seems that his tests also failed due to some dependency conflict with hadoop. Maybe can explain the details of the issue. In general, we use these maven build profiles ( http://maven.apache.org/guides/introduction/introduction-to-profiles.html) to control which modules of flink we are building and which dependencies we are adding. For example in the hadoop2 build, we add the "flink-yarn" and "flink-yarn-tests" modules. Also, the names of the hadoop dependencies have different names for hd1 and hd2. I'll get back to you once I've took a closer look into the issue.
