------------------------------------------------------------
[~leosun08], we can add a corner case that the node is added in suspect list
but probed succeed, then removed from the suspect list. I mean this is the case
of misreported node. Maybe cause by the restart node behavior in some real
scenarios.
Another one, can you address following this comment?

Can we rename dfsInputStreamNodes to suspectAndDeadNodes? It will look more
readable.
