Mingliang Liu commented on HADOOP-13239:
----------------------------------------

Thanks [~stevel@apache.org] for your review. This and [HADOOP-12709] together should address
the proposal for abandoning s3:// in {{trunk}} and {{branch-2}}.

> 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.
> [HADOOP-12709] cuts the s3:// from {{trunk}} branch, and this JIRA ticket is to deprecate
it from {{branch-2}}.
> # 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"
> Thanks [~stevel@apache.org] for the proposal.
