Yiqun Lin commented on HDFS-14651:
----------------------------------

For the second case, if we add the node to the dead node by mistake but it can 
quickly be probed and removed  from dfsinputstream in Detector. So this should 
not be a major problem, right?

> DeadNodeDetector checks dead node periodically
