> For a datanode in a pipeline, when its PacketResponder thread encounters an
> exception, it prints logs like below:
> 2019-10-24 09:22:58,212 WARN org.apache.hadoop.hdfs.server.datanode.DataNode:
> IOException in *BlockReceiver*.run():

> But this log is incorrect and misleading, the right print shoud be:
