>
> The {{LeaderGatewayRetrieval}} implementations {{AkkaJobManagerRetriever}}
> and the {{RpcGatewayRetriever}} should automatically retry failed gateway
> retrieval operations. This could be the case if the {{WebRuntimeMonitor}} is
> started before the actual Akka/RPC component. I would propose to retry it a
> fixed number of times with a short delay in between. If the resolution fails
> after exceeding the retries, a new retrieval operation will be started when
> requesting information from the {{WebRuntimeMonitor}} with FLINK-7533. This
> ensures that the retry operation won't run forever but also that it will
> eventually connect to the Akka/RPC component if it is existent.
