Steve Loughran commented on HDFS-13113:
---------------------------------------

this is in HDFS 3.1; leaving the JIRA open in case we want to add a patch which 
applies to branch-3.0; there's conflict in the NFS module

>          Issue Type: Improvement
>          Components: datanode, namenode, nfs
>    Affects Versions: 2.4.0
>            Reporter: Steve Loughran

> FYI, In HADOOP-10571, [~boky01] is going to clean up a lot of the log 
> statements, including some in Datanode and elsewhere.
> I'm provisionally +1 on that, but want to run it on the standalone tests 
> (Yetus has already done them), and give the HDFS developers warning of a 
> change which is going to touch their codebase.
> If anyone doesn't want the logging improvements, now is your chance to say so
