Rootcausing :Â proxyserver on RM can't be supported for Kerberos enabled cluster
because AuthenticationFilter is applied twice in Hadoop code (once in
httpServer2 for RM, and another instance from AmFilterInitializer for proxy
server). This will require code changes to hadoop-yarn-server-web-proxy project
