Hazem Mahmoud updated HDFS-8660:
--------------------------------
Status: Patch Available (was: Open)
> 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.
