> RouterRpcServer#invokeAtAvailableNs does not take effect when retrying. See
> HDFS-15543.
> The original code of RouterRpcServer#getNameSpaceInfo looks like this:
> {code:java}
> private Set<FederationNamespaceInfo> getNameSpaceInfo(String nsId) {
> Set<FederationNamespaceInfo> namespaceInfos = new HashSet<>();
> for (FederationNamespaceInfo ns : namespaceInfos) {
> if (!nsId.equals(ns.getNameserviceId())) {
> namespaceInfos.add(ns);
> }
> }
> return namespaceInfos;
> } {code}
> And _namespaceInfos_ is always empty here.
