----------------------------
hmmm, it seems I am working on a previous version of Flink, the latest version
does not have timeout any more. Let me see.
> Remove SlotRequest timeout
> --------------------------
>
> Key: FLINK-9778
> URL: https://issues.apache.org/jira/browse/FLINK-9778
> Project: Flink
> Issue Type: Improvement
> Components: JobManager, ResourceManager, TaskManager
> Reporter: 陈梓立
> Assignee: 陈梓立
> Priority: Major
> Fix For: 1.5.1
>
>
> Now when SlotPool(JobMaster) requestSlotsFromResourceManager, it checks
> timeout, if RM does not response in 5 minutes, JM fails the request and
> re-request it. It does little good and cause flink request resource less
> exactly.
> I would propose remove this timeout mechanism, that is, a SlotRequest does no
> more timeout. And our current failure tolerant mechanism would handle
> SlotRequest exception.
