[jira] [Updated] (FLINK-14233) All task state changes should be
notified to SchedulingStrategy (SchedulerNG)
[ https://issues.apache.org/jira/browse/FLINK-14233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhu Zhu updated FLINK-14233:
----------------------------
Description:
{{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 that some states are not supposed to be notified for certain concerns, we should document it in the interface.
