Regular checkpoints and savepoints complete > successfully, it is only the stop-with-savepoint request where this behavior > is seen. > > *Expected Behavior:* > The stop-with-savepoint request stops the job with a FINISHED state. > > *Actual Behavior:* > The stop-with-savepoint request either times out or hangs indefinitely unless > a message arrives in all the queues that the job consumes from after the > stop-with-savepoint request is made. > > *Current workaround:* > Send a sentinel value to each of the queues consumed by the job that the > deserialization schema checks in its isEndOfStream method. This is cumbersome > and makes it difficult to do stateful upgrades, as coordination with another > system is now necessary. > > > The TaskManager thread dump is attached. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
