> Router currently uses Namenode web resources to read and verify delegation
> tokens. This model doesn't work when router will be deployed in secured mode.
> This change will introduce router's own UserProvider resource and
> dependencies.
> In the current deployment one can see this exception.
> {"RemoteException":\{"exception":"ClassCastException","javaClassName":"java.lang.ClassCastException","message":"org.apache.hadoop.hdfs.server.federation.router.Router
> cannot be cast to org.apache.hadoop.hdfs.server.namenode.NameNode"}}
> In the proposed change, router will maintain its own web resource, that will
> be similar to current namenode, but modified to get back a router instance
> instead of namenode.
