-----------------------------------
Summary: Slow write to packet mirror should log which mirror and
which block
Key: HDFS-8660
URL: https://issues.apache.org/jira/browse/HDFS-8660
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.7.0
Reporter: Hazem Mahmoud
Assignee: Hazem Mahmoud
Currently, log format states something similar to:
"Slow BlockReceiver write packet to mirror took 468ms (threshold=300ms)"
For troubleshooting purposes, it would be good to have it mention which block
ID it's writing as well as the mirror (DN) that it's writing it to.
