"s3:" URLs break when Secret Key contains a slash, even if encoded
------------------------------------------------------------------

                 Key: HADOOP-3733
                 URL: https://issues.apache.org/jira/browse/HADOOP-3733
             Project: Hadoop Core
          Issue Type: Bug
          Components: fs/s3
    Affects Versions: 0.17.1
            Reporter: Stuart Sierra
            Priority: Minor


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:

$ bin/hadoop distcp file:///source  s3://RYWX12N9WCY42XVOL8WH:Xqj1%2FNMvKBhl1jqKlzbYJS66ua0e8z7Kkvptl9bv@mybucket/dest
