Summary: Add seqno in log when BlockReceiver receive packet
Key: HDFS-15733
URL: https://issues.apache.org/jira/browse/HDFS-15733
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Haibin Huang
Assignee: Haibin Huang
There is a debug log show when BlockReceiver receiving a new packet, however
now we can't tell which packet this debug log belongs to, i think it would be
better to add a sequence number in the log.
now the debug log like this, missing the seqno of packetÂ
{code:java}
2020-12-11,16:26:30,518 DEBUG org.apache.hadoop.hdfs.server.datanode.DataNode:
Receiving one packet for block BP-XXX:blk_XXX: PacketHeader with packetLen=2559
header data: offsetInBlock: 1
