jai1 opened a new issue #715: Introduce retry logic for creating producers and consumers
URL: https://github.com/apache/incubator-pulsar/issues/715
 
 
   ### Requirement
   Creation of Producer / Subscriber can fail due to:-
   a. Genuine issues
      - In correct serviceUrl
      - VIP down
      - incorrect topic name etc
   b. Intermittent issues
      - Broker Unloading a topic 
      - Broker shutting down
      - Intermittent network issues
      - connection Timeout due to GC pause.
   
   For the (b. Intermittent Issues) the client has no option but to backoff and retry.
   
   I think this is a common enough use case to introduce new APIs (to not break Binary compatibility) for createProducer and subscribe - which will be simple wrappers over the existing APIs. These APIs will take an additional parameter retrycount, they will just blindly retry after backoff. 
   
   @merlimat @rdhabalia @saandrews - Wanted to know your views on this.
