John Phelan commented on FLINK-21439:
-------------------------------------
Hi [~mapohl] [~rmetzger] could I ask what's going on with
[flink/AdaptiveSchedulerTest.java at master · apache/flink
(github.com)|https://github.com/apache/flink/blob/master/flink-runtime/src/test/java/org/apache/flink/runtime/scheduler/adaptive/AdaptiveSchedulerTest.java#L965]
then?
How come it is called in many places in that test if we never expect
{{updateTaskExecutionState}} to be called on {{AdaptiveScheduler}} with a
specific failing task?

> {{SchedulerNG.requestJob}} returns an {{ExecutionGraphInfo}} that was
> introduced in FLINK-21188. This {{ExecutionGraphInfo}} holds the information
> about the {{ArchivedExecutionGraph}} and exception history information.
> Currently, it's a list of {{ErrorInfos}}. This might change due to ongoing
> work in FLINK-21190 where we might introduced a wrapper class with more
> information on the failure.
> The goal of this ticket is to implement the exception history for the
> {{AdaptiveScheduler}}, i.e. collecting the exceptions that caused restarts.
> This collection of failures should be forwarded through
> {{SchedulerNG.requestJob}}.
