> {{TestBalancer}} is a big test by itself, it is also a part of many other tests. Running these tests involves spinning of {{MiniDFSCluter}} and shutting it down for every test case, which is inefficient. Many of the test cases can run using the same instance of {{MiniDFSCluter}}, but not all of them. Would be good to refactor the tests to optimize their running time.
