> URL: https://issues.apache.org/jira/browse/HADOOP-13387
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Attachments: HADOOP-13887-branch-2-001.patch
>
>
> The warning telling people not to use s3 appears during filesystem
> initialization -even if you aren't using the FS. This is because it is
> printed during static initialization, and when the FS code loads all
> available filesystems, that static code is inited.
> It needs to be moved into the init() code of an instance
