Assignee: Jane Chan
> SQL client hangs when executing EXECUTE PLAN
> --------------------------------------------
>
> Key: FLINK-32219
> URL: https://issues.apache.org/jira/browse/FLINK-32219
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Client
> Affects Versions: 1.17.1
> Reporter: Shuai Xu
> Assignee: Jane Chan
> Priority: Major
>
> I compiled a plan for an INSERT statement and executed the plan, but the SQL
> client became unresponsive when executing the EXECUTE PLAN statement. I
> confirmed that the Flink job is running normally by checking the Flink
> dashboard. The only issue is that the SQL client becomes stuck and cannot
> accept new commands. I printed the stack trace of the SQL client process, and
> here is a part of it for reference.
