> Most HDFS tests are functional tests that test a feature end to end by running a mini
cluster. We should add more tests like TestReplication that attempt to stress individual classes
in isolation, ie by stubbing out dependencies without running a mini cluster. This allows
for more fine-grain testing and making tests run much more quickly because they avoid the
cost of cluster setup and teardown. If it makes sense to use another framework besides junit
we should standardize with MAPREDUCE-1050.
