Summary: Revise PacketResponder's log.
Key: HDFS-14945
URL: https://issues.apache.org/jira/browse/HDFS-14945
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 3.1.3
Reporter: Xudong Cao
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:
2019-10-24 09:22:58,212 WARN org.apache.hadoop.hdfs.server.datanode.DataNode:
IOException in *PacketResponder*.run():
