-------------------------------
Summary: LazyFromSourcesSchedulingStrategy is possible to schedule
non-CREATED vertices
Key: FLINK-20285
URL: https://issues.apache.org/jira/browse/FLINK-20285
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.11.0
Reporter: Zhu Zhu
Fix For: 1.12.0, 1.11.3
LazyFromSourcesSchedulingStrategy is possible to schedule vertices which are
not in CREATED state. This will lead result in unexpected check failure and
result in fatal error[1].
The reason is that the status of a vertex to schedule was changed in
LazyFromSourcesSchedulingStrategy#allocateSlotsAndDeployExecutionVertices()
during the invocation of schedulerOperations.allocateSlotsAndDeploy(...) on
other vertices.
e.g. ev1 and ev2 are in the same pipelined region and are restarted one by one
in the scheduling loop in
LazyFromSourcesSchedulingStrategy#allocateSlotsAndDeployExecutionVertices().
They are all CREATED at the moment. ev1 is scheduled first but it immediately
fails due to some slot allocation error and ev2 will be canceled as a result.
So when ev2 is scheduled, its state would be CANCELED and the state check
failed.
