-------------------------------
Summary: All task state changes should be notified to
SchedulingStrategy (SchedulerNG)
Key: FLINK-14233
URL: https://issues.apache.org/jira/browse/FLINK-14233
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Affects Versions: 1.10.0
Reporter: Zhu Zhu
Fix For: 1.10.0
{{SchedulingStrategy}} requires task states to make scheduling decisions.
According to {{SchedulingStrategy#onExecutionStateChange}} definition, all task
state changes should be notified to {{SchedulingStrategy}}, including those
from TMs and from within JM.
This can be helpful for a more flexible scheduling.
In the worst case, if some states are not supposed to be notified for some
concerns, we should document it for that interface.
