Have a look at https://wiki.apache.org/hadoop/HowToDevelopUnitTests , which
(now) explains the miniclusters​ -which you can use for testing against
in-VM HDFS and YARN cluster simulations. Passing unit tests doesn't mean
your code works in a real cluster, but failing them does mean that it won't
-and they are great for both local and Jenkins-managed builds
