> Key: FLINK-19750
> URL: https://issues.apache.org/jira/browse/FLINK-19750
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kafka
> Affects Versions: 1.11.0, 1.11.1, 1.11.2
> Reporter: Qingsheng Ren
> Assignee: Qingsheng Ren

>
> When a job using Kafka consumer is recovered from a checkpoint or savepoint,
> the {{open}} method of the record deserializer is not called. This is
> possibly because {{this.deserializer.open}} is put into the else clause by
> mistake, which will only be called if the job has a clean start.
