-------------------------------
Summary: Fix the concurrent problem between triggering savepoint
with drain and finish
Key: FLINK-23884
URL: https://issues.apache.org/jira/browse/FLINK-23884
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Affects Versions: 1.14.0
Reporter: Yun Gao
Fix For: 1.14.0
Currently when triggering stop-with-savepoint --drain, we would like to first
finish the task and then trigger a savepoint. However, currently the implement
does not ensures triggering get successful before the task get finished and
close the mailbox, which might cause the savepoint fail.
