Summary: JWTRedirectAuthenticationHandler doesn't Retain Original
Query String
Key: HADOOP-12481
URL: https://issues.apache.org/jira/browse/HADOOP-12481
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Larry McCay
Assignee: Larry McCay
Fix For: 2.8.0
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.
