>             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)
