>                 Key: HADOOP-13873
>                 URL: https://issues.apache.org/jira/browse/HADOOP-13873
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: 2.8.0
>            Reporter: Steve Loughran
>            Priority: Minor
>
> HADOOP-13871 has shown that network problems can kill perf, and that it's v. hard to
track down, even if you turn up the logging in hadoop.fs.s3a and com.amazon layers to debug.
> we could maybe improve things by printing out the IPAddress of the s3 endpoint, as that
could help with the network tracing. Printing from within hadoop shows the one given to S3a,
not a different one returned by any load balancer.
