@tomscut Sir, thanks for your review.
> Class
org.apache.hadoop.hdfs.federation.protocol.proto.HdfsServerFederationProtos$RouterFederatedStateProto
defines non-transient non-serializable instance field namespaceStateIds_
I just renamed FederationProtocol.proto from hadoop-hdfs-rbf to
hadoop-hdfs-client, and didn't modify any content.
>
org.apache.hadoop.hdfs.ClientGSIContext.mergeRouterFederatedState(ByteString)
makes inefficient use of keySet iterator instead of entrySet iterator
I think this check is imprecise, because the key will be used. The related
code as bellows:
```
for (String ns : remoteMapping.keySet()) {
// Warning here.
long remoteValue = remoteMapping.get(ns);
long localValue = localMapping.getOrDefault(ns, 0L);
localMapping.put(ns, Math.max(remoteValue, localValue));
}
```
Do you have some good suggestions?
