> If the router receives an operation from a proxyUser, it drops the realUser in the UGI and makes the routerUser the realUser for the operation that goes to the namenode.
> In the namenode UGI logs, we'd like the ability to know the original realUser.
> The router should propagate the realUser from the client call as part of the callerContext.
