Steve Loughran updated HADOOP-14833:
------------------------------------
    Description: 
Remove the s3a://user:secret@host auth mechanism from S3a. 

As well as being insecure, it causes problems with S3Guard's URI matching code.

Proposed: cull it utterly. We've been telling people to stop using it since 
HADOOP-3733

  was:
Remove the s3a://user:secret@host auth mechanism from S3a

I think we could consider retain it as an explicit credential provider you can 
ask for, so that people who cannot move off it (yet) can reconfigure their 
system, but unless you do that, it stops working. 

We could add a dummy credential handler which recognises the user:secret 
pattern & then tells the user "no longer supported, sorry, here's how to 
migrate", & add that to the default chain after everything else.
