> Some tests may fail with NullPointerException since RaftTestUtil.waitForLeader(..) may return null (and the tests do not check for null) when leader elections take a long time.
> It seems RaftTestUtil.waitForLeader(..) better waits for a longer period and, if there is a no leader, throw an exception with some descriptive error message, instead of returning null.
