The other problem: TestLostTaskTracker is JUnit v3 test (it extends TestCase,
etc.). Please make it to be JUnit v4 (like the other two tests are).

> Using mock objects in unit tests can improve code quality (see e.g.
> http://www.mockobjects.com/). Hadoop would benefit from having a mock object
> framework for developers to write unit tests with. Doing so will allow a
> wider range of failure conditions to be tested and the tests will run faster.
