tillrohrmann commented on issue #6872: [FLINK-10436] Add 
ConfigOption#withFallbackKeys
URL: https://github.com/apache/flink/pull/6872#issuecomment-431055291
 
 
   The idea is that some options can default to some other option if they are 
not specified but the other option. Here concretely, it is the `rest.address` 
which is the same as the `jobmanager.rpc.address`. This of course only makes 
sense in the current setup, where the `RestServerEndpoint` runs in the same 
process as the `Dispatcher`. In the future, this might change and could require 
to remove the fallback dependency depending on what the default behaviour is.
