Java: OpenJdk 11 Kafka: 2.2.0 Kafka streams lib: 2.3.0
I am trying to deploy my Kafka streams application in a docker container and it fails while trying to create an internal state store with a TopicAuthorizationException. It works well locally. The main difference between locally and on the server is that there it connects to a server deployed Kafka and authenticates using the usual Kerberos auth. I fail to understand the link between authentication and the local stores.
My stream looks like that:
StreamsBuilder builder = new StreamsBuilder();
//We stream from the source topic
KStream<String, EnrichedMessagePayload> sourceMessagesStream = builder.stream(sourceTopic, Consumed
.with(Serdes.serdeFrom(String.class), INPUT_SERDE));
//We group per room and window
TimeWindowedKStream<String, EnrichedMessagePayload> windowed = sourceMessagesStream
.groupByKey().windowedBy(TimeWindows.of(Duration.ofMillis(windowSize)).grace(Duration.ZERO));
//We make them a list
KStream<Windowed<String>, WindowedMessages> grouped = windowed
.aggregate(WindowedMessages::new,
(key, value, aggregate) -> aggregate.add(value),
Materialized.with(Serdes.String(), Serdes.serdeFrom(windowSerializer, windowSerializer)))
.suppress(Suppressed.untilWindowCloses(unbounded()))
.toStream();
//Filter
KStream<Windowed<String>, FilterResult> filtered = grouped
.mapValues((readOnlyKey, value) -> filterWindow(value.getMessages()));
//Re map to its original form
KStream<String, OutputPayload> reduced = filtered
.flatMap((KeyValueMapper<Windowed<String>, WindowedMessages, Iterable<KeyValue<String, OutputPayload>>>) (key, value) -> value
.getMessages()
.stream().map(payload -> new KeyValue<>(key.key(), payload))
.collect(toList()));
//Target topic
reduced.to(sinkTopic, Produced
.with(Serdes.serdeFrom(String.class), SERDE));
return builder.build();
It receives a stream of messages, windows it, aggregates all the messages per window, keeps only the last version of the list with a 'Suppressed' and then flatMaps the whole to forward it to another topic.
Every time i get that kind of exception:
