I waited to revert for a long time to ensure that this is working as expected. I am VERY HAPPY to tell you that this configuration change has fixed this issue! Not a single task has failed for over 2 weeks!

THANKS once again. Hopefully, at some point we can switch to Spark 3.0.

We've invested quite an effort in the latest releases into streaming and hope there will be less and less headaches like this.

"spark.kafka.producer.cache.timeout" is available since 2.2.1 which can be increased as a temporary workaround.
This is not super elegant but works which gives enough time to migrate to Spark 3.

I must say.. Spark has let me down in this case. I am surprised an important issue like this hasn't been fixed in Spark 2.4.

I am fighting a battle of 'Spark Structured Streaming' Vs 'Flink' at work & now because Spark 2.4 can't handle this I've been asked to rewrite the code in Flink.

Moving to Spark 3.0 is not an easy option 'cause Cloudera 6.2 doesn't have a Spark 3.0 parcel!!!! So we can't upgrade to 3.0.

So sad. Let me ask one more time. Is there no way to fix this in Spark 2.4?

BTW, we are seeing this message as well: "org.apache.kafka.common.KafkaException: Producer closed while send in progress". I am assuming this happens because of the previous issue.."producer has been closed", right? Or are they unrelated? Please advise. Thanks.

Which Spark version do you use? There's a known issue on Kafka producer pool in Spark 2.x which was fixed in Spark 3.0, so you'd like to check whether your case is bound to the known issue or not.

I know this is related to Kafka but it happens during the Spark Structured Streaming job that's why I am asking on this mailing list.

How would you debug this or get around this in Spark Structured Streaming? Any tips would be appreciated. Thanks.
