Steve Loughran created HADOOP-15955:
---------------------------------------
Summary: declare that fs.s3a.ext. is a prefix for arbitrary
extensions
Key: HADOOP-15955
URL: https://issues.apache.org/jira/browse/HADOOP-15955
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.2.0
Reporter: Steve Loughran
it turns out to be useful to use per-bucket config extensions for things like
delegation tokens.
To avoid third-party extensions to pollute the fs.s3a. namespace with their own
config options (So meaning its inevitable things break when we add some new fs
option), I propose the following policy
# applications/extensions MUST NOT add their own config options under fs.s3a.
# anyone is free to use "fs.s3a.ext.$product." options in s3a.
# we promise not to go near those options in the S3A module
# it is left to people who add their own settings here to avoid clashing with
others, This is why you should use a unique product name
With this specified (where?) then if someone uses some fs.s3a. option which
gets broken by an updated s3a connector, well, we say "wontfix", —and indeed,
get to tell them off for doing this.
Propose: similar for the other stores
