We have confirmed that the release-1.10 blocker FLINK-15456 is actually caused
by the problem described in this ticket.
Since this problem is not introduced in 1.10, I believe it should not be a
blocker. But how do we fix the problem, and whether it needs to be fixed in
1.10 still need to be discussed.
I'm setting this ticket to be release-1.10 critical for now, to avoid
overlooking it before a decision being made.

> URL: https://issues.apache.org/jira/browse/FLINK-13554
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.9.0
> Reporter: Xintong Song
> Priority: Critical
> Fix For: 1.10.0
>
>
> Recently, we encountered a case that one TaskExecutor get stuck during
> launching on Yarn (without fail), causing that job cannot recover from
> continuous failovers.
> The reason the TaskExecutor gets stuck is due to our environment problem. The
> TaskExecutor gets stuck somewhere after the ResourceManager starts the
> TaskExecutor and waiting for the TaskExecutor to be brought up and register.
> Later when the slot request timeouts, the job fails over and requests slots
> from ResourceManager again, the ResourceManager still see a TaskExecutor (the
> stuck one) is being started and will not request new container from Yarn.
> Therefore, the job can not recover from failure.
> I think to avoid such unrecoverable status, the ResourceManager need to have
> a timeout on starting new TaskExecutor. If the starting of TaskExecutor takes
> too long, it should just fail the TaskExecutor and starts a new one.
