Till Rohrmann commented on FLINK-18959:
---------------------------------------
Yes exactly. The scope of this ticket is to fix the current regression which
means to that cancelling a job should still trigger its archiving.
> Fail to archiveExecutionGraph because job is not finished when dispatcher
> close

> After digging into the problem, I find that the function

> {panel}
> From the log, we can see that job is not finished when dispatcher closes. The
> process is as following:
> * Receive cancel command and send it to all tasks async.
> * In MiniDispatcher, begin to shutting down per-job cluster.
> * Stopping dispatcher and remove job.
> * Job is cancelled and callback is executed in method startJobManagerRunner.
> * Because job is removed before, so currentJobManagerRunner is null which
> not equals to the original jobManagerRunner. In this case,
> archivedExecutionGraph will not be uploaded.
> In normal cases, I find that job is cancelled first and then dispatcher is
> stopped so that archivedExecutionGraph will succeed. But I think that the
> order is not constrained and it is hard to know which comes first.
> Above is what I suspected. If so, then we should fix it.
