[jira] [Created] (HDFS-8660) Slow write to packet mirror should log which mirror and which block

Hazem Mahmoud created HDFS-8660:
-----------------------------------

             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.
