Review comment:
just a thought. it would be great if we can refactor the MiniDfsCluster,
the NameNode, FSNamesystem and EditLogTailer such that they take a FakeTimer as
a parameter during initialization. If all the tests adopt the way of FakeTimer
we wouldn't have so many flaky tests. But I reckon it's out of scope of this
change.
