             Fix For: 0.6


In the Dal timeframe Knox would like to be able to expose the Falcon REST API via the gateway. In order for that to work securely it must be possible to setup a trust relationship between Knox and Falcon. This is commonly done in other Hadoop ecosystem components using a combination of Kerberos/SPNego and a doas URL query parameter. This provides a mechanism for Falcon to strongly authenticate Knox as a trusted proxy, ensuring that it can trust the identity assertions made via the doas query parameter. The links below provide some information describing how this is done for core Hadoop. Also note that most components utilize Hadoop core's reusable hadoop-auth module to implement this functionality.
