Description

Router is using HDFSPolicyProvider. We can't add new protocol in this class for router, its better to create in policy provider for Router.

// Set service-level authorization security policy
if (conf.getBoolean(HADOOP_SECURITY_AUTHORIZATION, false)) {
this.adminServer.refreshServiceAcl(conf, new HDFSPolicyProvider());
}

I got this issue when I am verified HDFS-14079 with secure cluster.

./bin/hdfs dfsrouteradmin -ls /
ls: Protocol interface org.apache.hadoop.hdfs.protocolPB.RouterAdminProtocol is not known.
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): Protocol interface org.apache.hadoop.hdfs.protocolPB.RouterAdminProtocol is not known.
