------------------------------------
Resolution: Duplicate
> FlinkKinesisConsumer should not interrupt the legacy source thread in cancel
> ----------------------------------------------------------------------------
>
> Key: FLINK-23538
> URL: https://issues.apache.org/jira/browse/FLINK-23538
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kinesis
> Reporter: Dawid Wysakowicz
> Priority: Critical
> Fix For: 1.14.0
>
>
> We use {{SourceFunction#cancel()}} not just to forcefully cancel the source
> thread, but also to gracefully stop the legacy source function in order to
> perform e.g. the {{stop-with-savepoint}}. Therefore we want to clarify the
> contract of {{cancel()}} and force it to be a graceful cancel.
> Currently the FlinkKinesisConsumer is the only known source that does not
> perform a graceful stop there, but instead it interrupts the legacy source
> thread.
