Lisheng Sun commented on HDFS-14651:
------------------------------------
To add suspicious list‘s main purpose is to distinguish between the two cases.
The priority for handling these two situations should be different and will not
affect each other.
And the datanode in suspicious is accessed by other dfsinputstream, the
datanode in dead list is not accessed by other dfsinputstream
> DeadNodeDetector checks dead node periodically
