---------------------------------

             Summary: 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.
