The filer does not set defaultReplication to the defaultReplication o… ()
The filer does not set defaultReplication to the defaultReplication of the master (it is not necessary, because if the filer is not set, the configuration of the master will be used when calling Assign), otherwise, when the defaultReplication of the master is modified and all master nodes are restarted, the defaultReplication will not take effect (because the filer Keep the previous defaultReplication setting from the master)
