> This Jira constructs DeadNodeDetector state machine model. The function it
> implements as follow:
> # After DFSInputstream detects some DataNode die, it put in DeadNodeDetector
> and share this information to others in the same DFSClient. The ohter
> DFSInputstreams will not read this DataNode.
> # DeadNodeDetector also have DFSInputstream reference relationships to each
> DataNode. When DFSInputstream close, DeadNodeDetector also remove this
> reference. If some DeadNode of DeadNodeDetector is not read by
> DFSInputstream, it also is removed from DeadNodeDetector.
