Blocker Description
The Jenkins builds fail with a NoClassDefFoundError, see build #3376 log. The missing class org/mockito/stubbing/Answer is part of build/test/lib/mockito-core-1.9.5.jar which was a dependency of mrunit (screenshot mrunit-deps-cached.png). After removing mrunit from my local ivy cache (rm -rf ~/.ivy2/cache/org.apache.mrunit/ mrunit lost mockito as dependency (screenshot mrunit-deps-new.png) and the build failure is reproducible.
I don't understand what triggered the loss of the transitive dependency: the upgrade to Hadoop 2.7.2 (NUTCH-2236) or the addition of maven:classifier="hadoop2" in commit 7956daee.
