Larry McCay commented on HADOOP-11717:
--------------------------------------
[~wheat9] - There is only one source file here. :)
There is no infrastructure beyond the preexisting
AltKerberosAuthenticationHandler.
I certainly agree that code reuse would be great and if/when we add an OAuth
handler we should determine if we should refactor. In the meantime, there is no
point in prematurely doing so in a way that may not work when we go to use it
anyway.

> Extend AltKerberosAuthenticationHandler to provide WebSSO flow for UIs.
> The actual authentication is done by some external service that the handler
> will redirect to when there is no hadoop.auth cookie and no JWT token found
> in the incoming request.
> Using JWT provides a number of benefits:
> * It is not tied to any specific authentication mechanism - so buys us many
> SSO integrations
> * It is cryptographically verifiable for determining whether it can be trusted
> * Checking for expiration allows for a limited lifetime and window for
> compromised use
> This will introduce the use of nimbus-jose-jwt library for processing,
> validating and parsing JWT tokens.
