             Summary: RBF: Support to get Router object from web context instead of Namenode
                 Key: HDFS-14006
                 URL: https://issues.apache.org/jira/browse/HDFS-14006
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: CR Hota
            Assignee: CR Hota


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.
