>                 URL: https://issues.apache.org/jira/browse/FLINK-3335
>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Runtime
>    Affects Versions: 1.0.0

> 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.
