Till Rohrmann created FLINK-20095:
-------------------------------------
Summary: SchedulerBase.stopWithSavepoint schedules operation after
ExecutionGraph terminates
Key: FLINK-20095
URL: https://issues.apache.org/jira/browse/FLINK-20095
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.12.0
Reporter: Till Rohrmann
Fix For: 1.13.0
While looking into FLINK-20065, we realized that we cannot implement the change
described in FLINK-20094 because the {{SchedulerBase}} schedules an
asynchronous operation after the termination of the {{ExecutionGraph}}. This
asynchronous operation needs to complete before the savepoint path is returned.
In order to solve FLINK-20094, we either need to keep track of these operations
and suspend the {{SchedulerBase}} termination until all operations have
completed or we might be to return the savepoint path without depending it on
the completion of the {{handleAsync}} here:
https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/scheduler/SchedulerBase.java#L921.
