> 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:

> 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.
