Subject [jira] [Commented] (HADOOP-14114) S3A can no longer handle unencoded + in URIs

Steve Loughran commented on HADOOP-14114:
-----------------------------------------

thx. Note that with per bucket config, there's no justification for secrets in URIs no more.
You can do a distcp using -D options to declare (ideally session) credentials for the URL
you are working with, same for anything else

> Amazon secret access keys can include alphanumeric characters, but also / and + (I wish
there was an official source that was really specific on what they can contain, but I'll have
to rely on a few blog posts and my own experience).
> Keys containing slashes used to be impossible to embed in the URL (e.g. s3a://access_key:secret_key@bucket/)
but it is now possible to do it via URL encoding. Pluses used to work, but that is now *only*
possible via URL encoding.
> In the case of pluses, they don't appear to cause any other problems for parsing. So
IMO the best all-around solution here is for people to URL-encode these keys always, but so
that keys that used to work just fine can continue to work fine, all we need to do is detect
that, log a warning, and we can re-encode it for the user.
