--------------------------------------
Summary: Deprecate s3:// in branch-2
Key: HADOOP-13239
URL: https://issues.apache.org/jira/browse/HADOOP-13239
Project: Hadoop Common
Issue Type: Improvement
Components: fs/s3
Affects Versions: 2.8.0
Reporter: Mingliang Liu
Assignee: Mingliang Liu
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.
