{{core-default.xml}} updated.
> Deprecate s3:// in branch-2,; cut from trunk
> --------------------------------------------
>
> Key: HADOOP-12709
> URL: https://issues.apache.org/jira/browse/HADOOP-12709
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/s3
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Mingliang Liu
> Attachments: HADOOP-12709.000.patch

>
> The fact that s3:// was broken in Hadoop 2.7 *and nobody noticed until now*
> shows that it's not being used. while invaluable at the time, s3n and
> especially s3a render it obsolete except for reading existing data.
> I propose
> # Mark Java source as {{@deprecated}}
> # Warn the first time in a JVM that an S3 instance is created, "deprecated
> -will be removed in future releases"
> # in Hadoop trunk we really cut it. Maybe have an attic project (external?)
> which holds it for anyone who still wants it. Or: retain the code but remove
> the {{fs.s3.impl}} config option, so you have to explicitly add it for use.
