> If brokers are not available and we try to shut down connect workers, sink connectors will be stuck in a loop retrying to commit offsets:
> 2016-10-17 09:39:14,907] INFO Marking the coordinator 192.168.1.9:9092 (id: 2147483647 rack: null) dead for group connect-dump-kafka-config1 (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:600)
> [2016-10-17 09:39:14,907] ERROR Commit of WorkerSinkTask{id=dump-kafka-config1-0} offsets threw an unexpected exception:  (org.apache.kafka.connect.runtime.WorkerSinkTask:194)
> org.apache.kafka.clients.consumer.RetriableCommitFailedException: Offset commit failed with a retriable exception. You should retry committing offsets.
> Caused by: org.apache.kafka.common.errors.GroupCoordinatorNotAvailableException
> We should probably limit the number of retries before doing "unclean" shutdown.
