Sergei Morozov updated FLINK-36407:
-----------------------------------
Attachment: Flink36407Reproducer.java
> SchemaRegistry doesn't shutdown its underlying ExecutorService upon closing
> ---------------------------------------------------------------------------
>
> Key: FLINK-36407
> URL: https://issues.apache.org/jira/browse/FLINK-36407
> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Affects Versions: cdc-3.2.0
> Reporter: Sergei Morozov
> Priority: Minor
> Attachments: Flink36407Reproducer.java
>
>
> The {{SchemaRegistry}} class exclusively uses an {{ExecutorService}}
> referenced by the {{coordinatorExecutor}} field, but when the schema registry
> closes, the service remains running. As a result, a program running a Flink
> CDC pipeline never terminates.
> For some reason, it's not reproducible with the existing integration tests
> but is reproducible with the attached program.
> Once {{execution.execute()}} returns, it prints the following and never
> terminates.
> {quote}
> Thread[schema-evolution-coordinator,5,main] is still running
