Sendoh updated FLINK-5368: -------------------------- Description: As a developer when reading data from many topics, I want Kafka consumer to show something if any topic is not available. The motivation is we read many topics as list at one time, and sometimes we fail to recognize that one or two topics' names have been changed or deprecated, and Flink Kafka connector doesn't show the error. My proposed change would be either to throw RuntimeException or to use LOG.error(topic + "doesn't have any partition") if partitionsForTopic is null at this function. https://github.com/apache/flink/blob/master/flink-connectors/flink-connector-kafka-0.9/src/main/java/org/apache/flink/streaming/connectors/kafka/FlinkKafkaConsumer09.java#L208 Any suggestion is welcome. was: As a developer when reading data from many topics, I want Kafka consumer show something if any topic is not available.
