Hello, For your information, yesterday I upgraded our preproduction cluster from Storm 1.2.0 SNAPSHOT of December 2017 to 1.2.0 Release Candidate 4. Our alerting system based on Storm behaved quite bad with 1.2.0 RC4, and this morning, one of our team member noticed this message in our topologie's startup logs:
Advertising
1279 [main] WARN o.a.s.k.s.KafkaSpoutConfig - The KafkaConsumer enable.auto.commit setting is not supported. You can configure similar behavior through KafkaSpoutConfig.Builder.setProcessingGuarantee.This will be treated as an error in the next major release. 1279 [main] INFO o.a.s.k.s.KafkaSpoutConfig - Setting Kafka consumer property 'enable.auto.commit' to 'false', because the spout does not support auto-commit So I will resume our tests with this new setting and I will feedback once I have enought uptime on our "large preproduction cluster" with 1.2.0 RC4. Note: may I suggest to make this breaking change visible in Storm 1.2.0 releases notes? this is quite impacting. Or event better: make the topologies unable to start when they use such a removed property, so that at least people aren't fooled until they wonder why their Kafka spouts aren't anymore behaving like before and check logs? More to come when my preproduction tests will have been completed (1or 2 days needed). Best regards, Alexandre 2018-02-07 23:24 GMT+01:00 P.
