--------------------------------------

             Summary: Restart connectors after RetriableException raised from Task::start()
                 Key: KAFKA-13485
                 URL: https://issues.apache.org/jira/browse/KAFKA-13485
             Project: Kafka
          Issue Type: Improvement
          Components: KafkaConnect
            Reporter: Gunnar Morling


If a {{RetriableException}} is raised from {{Task::start()}}, this doesn't trigger an attempt to start that connector again. I.e. the restart functionality currently is only implemented for exceptions raised from {{poll()}}/{{put()}}. Triggering restarts also upon failures during {{start()}} would be desirable, so to circumvent temporary failure conditions like a network hickup which currrently require a manual restart of the affected tasks, if a connector for instance establishes a database connection during {{start()}}.
