Íñigo Goiri commented on HDFS-14006:
------------------------------------
Eventually we may want to take some of JspHelper and make it static and just
used from the new RouterJspHelper.
We can repurpose this JIRA for that once we have a clear understanding on what
can be reused.
Anyway, in my mind this JIRA should only be a refactor eventually.
> 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
> Priority: Major
>
> 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.
