Daniel Fritsi commented on HADOOP-18120:
----------------------------------------
[~weichiu], I won't be able to handle this ticket, sorry. I don't have time
right now. That's why I mentioned that it would be great if someone else could
check it. Since the coding part is pretty much done, there's not much left.
> Hadoop auth does not handle HTTP Headers in a case-insensitive way
> ------------------------------------------------------------------
>
> Key: HADOOP-18120
> URL: https://issues.apache.org/jira/browse/HADOOP-18120
> Project: Hadoop Common
> Issue Type: Bug
> Components: auth
> Reporter: Daniel Fritsi
> Priority: Critical
> Attachments: hadoop-auth-headers.patch
>
>
> According to [RFC-2616|https://www.ietf.org/rfc/rfc2616.txt] HTTP Headers are
> case-insensitive. There are proxies / load balancers (e.g.: newer versions of
> HA-proxy) which deliberately make some of the HTTP headers lower-case results
> in an authentication / authorization failure inside the Hadoop codebase.
> I've created a small patch (I'm from Cloudera):
> [^hadoop-auth-headers.patch]. This resolves our authentication issue. Can
> someone please have a look at this?
