------------------------------------------------------------------------
I believe this is because HDFS-16756 hasn't been backported to branch-3.3.
The proxyUser that has the routerUser as its realUser is created here
[https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-rbf/src/main/java/org/apache/hadoop/hdfs/server/federation/router/RouterRpcClient.java#L392]
In TestRouterRPC.java I added extra configs that make _*this.enableProxyUser*_
be true. I did this for simplicity rather that using a secure MiniDFSCluster.

> Project: Hadoop HDFS
> Issue Type: Task

> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0, 3.3.6

>
> 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.
