> This is some code cleanup separate from HDFS-8272:
> # Avoid duplicated block reader creation code
> # If no new source DN can be found, {{getBestNodeDNAddrPair}} returns null instead of
throwing Exception. Whether to throw Exception or not should be determined by {{getBestNodeDNAddrPair}}'s
caller.
