[jira] [Updated] (HADOOP-13239) Deprecate s3:// in branch-2
[ https://issues.apache.org/jira/browse/HADOOP-13239?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mingliang Liu updated HADOOP-13239:
-----------------------------------
Description:
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.

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.
