Konstantin Boudnik updated HDFS-669:
------------------------------------
Attachment: HDFS-669.patch
This patch version is based on the original posted by Eli. The following
modifications were made:
- patch is merged with current trunk
- true unit tests (as in FSNamesystem) are being placed under {{src/test/unit}}
- new build target 'run-test-unit' has been added to run unit tests only. This
target is also included into {{test-core}}
- original test is fixed and moved under {{src/test/unit}} from its original
location

> 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.
