> Confusing error about ManualTimestampSourceFunction
> ---------------------------------------------------
>
> Key: FLINK-3082
> URL: https://issues.apache.org/jira/browse/FLINK-3082
> Project: Flink
> Issue Type: Bug
> Reporter: Niels Basjes
> Assignee: Niels Basjes
>
> I wrote a source like this:
> {code}
> public class Foo extends RichSourceFunction<Bar> {
> {code}
> and then did
> {code}
> ctx.collectWithTimestamp(event, event.eventTimestamp);
> {code}
> I got this error:
> {code}
> Caused by: java.lang.UnsupportedOperationException: Automatic-Timestamp
> sources cannot emit elements with a timestamp. See interface
> ManualTimestampSourceFunction if you want to manually assign timestamps to
> elements.
> at
> org.apache.flink.streaming.api.operators.StreamSource$NonTimestampContext.collectWithTimestamp(StreamSource.java:97)
> {code}
> After some digging it turns out that {{ManualTimestampSourceFunction}} was
> renamed to {{EventTimeSourceFunction}} and apparently the old name still
> lingers in this error message.
