Sendoh updated FLINK-5368:
--------------------------
Description:
As a developer when reading data from many topics, I want Kafka consumer to
throw Exception or LOG.error() 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.
