Description

When StandbyNN triggers the rolling log, it sends a request to the remote NameNode.
Here are some log information:
'
2021-11-05 10:47:06,312 [3080066887]-INFO [Edit log tailer:EditLogTailer@316]-Triggering log roll on remote NameNode
2021-11-05 10:49:14,946 [3080195521]-INFO [Edit log tailer:EditLogTailer@316]-Triggering log roll on remote NameNode
2021-11-05 10:51:19,254 [3080319829]-INFO [Edit log tailer:EditLogTailer@316]-Triggering log roll on remote NameNode
'
The specific remote NameNode information cannot be seen from here. We can try to record the specific address.
