-----------------------------
Resolution: Won't Fix
> Fix DataSourceTask object reuse when disabled
> ---------------------------------------------
>
> Key: FLINK-3335
> URL: https://issues.apache.org/jira/browse/FLINK-3335
> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime
> Affects Versions: 1.0.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
>
> From {{DataSourceTask.invoke()}}:
> {code}
> if ((returned = format.nextRecord(serializer.createInstance())) != null) {
> output.collect(returned);
> }
> {code}
> The returned value ({{returned}}) must be copied rather than creating and
> passing in a new instance. The {{InputFormat}} interface only permits the
> given object to be used and does not require a new object to be returned
> otherwise.
