---------------------------------
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.
