> 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.
