Steve Loughran commented on HADOOP-14738:
-----------------------------------------
I'm doing this with the doc updates of HADOOP-14826m as they all go together,
and marking jets3t.jar as provided, so it doesn't go downstream any more,
targeting 3.0
FWIW, I can see nobody has been running the s3n tests for a while, as the new
tests from HADOOP-14397 are failing. I'll handle that here too

> Deprecate S3N in hadoop 3.0/2,9, target removal in Hadoop 3.1
> -------------------------------------------------------------
>
> Key: HADOOP-14738
> URL: https://issues.apache.org/jira/browse/HADOOP-14738
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.9.0, 3.0.0-beta1
> Reporter: Steve Loughran
> Priority: Blocker
>
> We are all happy with S3A; it's been stable since Hadoop 2.7 and high-perf
> since Hadoop 2.8
> It's now time to kill S3N off, remove the source, the tests, the transitive
> dependencies.
> I propose that in Hadoop 3.0 beta we tell people off from using it, and link
> to a doc page (wiki?) about how to migrate (Change URLs, update config ops).
