[jira] [Commented] (HADOOP-18120) Hadoop auth does not handle HTTP Headers in a case-insensitive way

------------------------------------------

It would be nice to add a test to it.

> 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?
