Bartosz Mikulski updated FLINK-29094:
-------------------------------------
Affects Version/s: 1.15.0
> Cannot stop Python job with savepoint when using Kafka Consumer
> ---------------------------------------------------------------
>
> Key: FLINK-29094
> URL: https://issues.apache.org/jira/browse/FLINK-29094
> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.15.0, 1.15.1
> Environment: Local Environment
> * OS: Ubuntu 20.04
> * Java: openjdk version "11.0.12" 2021-07-20
> * Flink: 1.15.1 (clean instalation)
> * Kafka: kafka_2.13-2.8.1
> Reporter: Bartosz Mikulski
> Priority: Major
>
> We want to gracefully stop a Python job reading from Kafka. However, running
> `flink stop --savepointPath` causes an exception to be thrown and the job
> fails. Find the exception in the
> [Gist|https://gist.github.com/BartMiki/6eab470a49d8a935ed3e7e544c3f278f#file-exception-txt].
> The type of savepoint also doesn't matter both canonical and native fail.
> This Stack Overflow [answer|https://stackoverflow.com/a/68280329] also does
> not work.
> However, checkpoints work fine. This leads to weird scenarios when you want
> to stop a Python job, stopping fails with an exception, and the job is
> restarted from the latest checkpoint.
> The setup was tested in fresh default Flink 1.15.1 installation (however we
> also tried 1.15.0 with the same error). The error occurred regardless of the
> amount of data processed from Kafka (could be even none). [Gist with minimal
> code required to trigger the
> exception|https://gist.github.com/BartMiki/6eab470a49d8a935ed3e7e544c3f278f].
