Hi,
When you say that the `JobManager` goes down, you're referring to the fact that
the Flink job will finish in a failed state after too many exceptions have
occurred in the `FlinkKafkaConsumer. Is that correct?
--> Yes, this is exactly what I meant, the Flink job is in a failed state
I'm afraid right now there is no code path that would allow catching those
`TopicUnthaurizationException`. We basically treat most exceptions coming from
Kafka as errors that require recovery.
--> We can have other exceptions, like like TimeoutException when our Kafka
brokers are degraded.
What behaviour would you have in mind as a reaction to those exceptions?
--> Our processing System is supposed to continue streaming data even though
there is some Kafka errors, we are expecting that the KafkaConsumer fails but
not the Flink job, do you think it is possible?
Best,
Aljoscha
