      Description

      Error Message
      Unfinished stubbing detected here:
      -> at org.apache.hadoop.hdfs.server.balancer.TestBalancer.spyFSNamesystem(TestBalancer.java:1948)
      
      E.g. thenReturn() may be missing.
      Examples of correct stubbing:
          when(mock.isOk()).thenReturn(true);
          when(mock.isOk()).thenThrow(exception);
          doThrow(exception).when(mock).someVoidMethod();
      Hints:
       1. missing thenReturn()
       2. although stubbed methods may return mocks, you cannot inline mock creation (mock()) call inside a thenReturn method (see issue 53)
