[jira] [Created] (KAFKA-5485) Streams should not suspend tasks twice

Matthias J. Sax created KAFKA-5485:
--------------------------------------

             Summary: Streams should not suspend tasks twice
                 Key: KAFKA-5485
                 URL: https://issues.apache.org/jira/browse/KAFKA-5485
             Project: Kafka
          Issue Type: Improvement
          Components: streams
    Affects Versions: 0.11.1.0
            Reporter: Matthias J. Sax
            Assignee: Matthias J. Sax
            Priority: Minor


Currently, Streams suspends tasks on rebalance and closes suspended tasks if not reassigned. During close, {{suspend()}} is called a second time, also calling {{Processor.close()}} for all nodes again.

It would be safer to only call {{suspend()}} once in case users have non-idempotent operations in {{Processor.close()}} method and might thus fail. (cf. KAFKA-5167)
