Subject [jira] [Commented] (HADOOP-3733) "s3:" URLs break when Secret Key contains a slash, even if encoded
Date Wed, 02 Aug 2017 09:04:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16110580#comment-16110580

Steve Loughran commented on HADOOP-3733:
----------------------------------------

I think that seems a reasonable strategy. Can you supply a patch on the HADOOP-14439 JIRA.
We should also look and see if that fixes spark's issues

> When using URLs of the form s3://ID:SECRET@BUCKET/ at the command line, distcp fails
if the SECRET contains a slash, even when the slash is URL-encoded as %2F.
> Say your AWS Access Key ID is RYWX12N9WCY42XVOL8WH
> And your AWS Secret Key is Xqj1/NMvKBhl1jqKlzbYJS66ua0e8z7Kkvptl9bv
> And your bucket is called "mybucket"
> You can URL-encode the Secret KKey as Xqj1%2FNMvKBhl1jqKlzbYJS66ua0e8z7Kkvptl9bv
> But this doesn't work:
