-------------------------------------------------------------
Makes sense to me to implement.
Well merging all the results for NN is also straight forward :
In RouterRpc :
{code:java}
@Override
public String[] getGroupsForUser(String user) throws IOException {
checkOperation(OperationCategory.READ);
RemoteMethod method = new RemoteMethod(GetUserMappingsProtocol.class,
"getGroupsForUser", new Class<?>[] {String.class}, user);
Set<FederationNamespaceInfo> nss = namenodeResolver.getNamespaces();
Map<FederationNamespaceInfo, String[]> results =
rpcClient.invokeConcurrent(nss, method, String[].class);
return merge(results, String.class);
}
{code}
We may do something like this?
It will also require to add a new method in {{ConnectionPool.java}} similar to
{{newClientConnection()}} and {{newNamenodeConnection()}}

> We configure hadoop.proxyuser.xx.yy ,then execute hdfs dfsadmin
> -Dfs.defaultFS=hdfs://router-fed -refreshSuperUserGroupsConfiguration,
> it throws "Unknown protocol: ...RefreshUserMappingProtocol".
> RouterAdminServer should support RefreshUserMappingsProtocol , or a proxyuser
> client would be refused to impersonate.As shown in the screenshot
