Review comment:
Yes, exactly, @ayushtkn. All of the DN will have the same NN and then
they will log the same thread name string.
For adding DN address, I'm not sure which fields in DN are considered stable
for this purpose. Maybe `setName("Command processor for " +
dn.getDisplayName());` will work?
