Description

Here are some logs recorded by the NameNode when using RBF:

2022-07-28 19:31:07,126 INFO ipc.Server: IPC Server handler 8 on default port 8020, call Call#127 Retry#0 org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from 172.10.100.67:58001

The ip information here is still the router. If the real client ip is recorded, it will more clearly express where the request comes from.
E.g:

2022-07-29 19:31:07,126 INFO ipc.Server: IPC Server handler 8 on default port 8020, call Call#127 Retry#0 org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from 172.10.100.67:58001, client=172.111.65.123:43232
