--------------------------------------
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()}}.
