>                 URL: https://issues.apache.org/jira/browse/KAFKA-13139
>             Project: Kafka
>          Issue Type: Bug
>          Components: KafkaConnect
>    Affects Versions: 3.0.0
>            Reporter: Konstantine Karantasis
>            Assignee: Konstantine Karantasis
>            Priority: Blocker
>             Fix For: 3.0.0
>
>
> After https://issues.apache.org/jira/browse/KAFKA-4793 a response to restart only the connector (without any tasks) returns OK with an empty body. 
> As system test runs revealed, this causes an NPE in [https://github.com/apache/kafka/blob/trunk/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/rest/RestClient.java#L135]
> We should return 204 (NO_CONTENT) instead. 
> This is a regression from previous behavior, therefore the ticket is marked as a blocker candidate for 3.0
