[jira] [Commented] (FLINK-9778) Remove SlotRequest timeout

    [ https://issues.apache.org/jira/browse/FLINK-9778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16536589#comment-16536589 ] 

陈梓立 commented on FLINK-9778:
----------------------------

I will pull a PR a little later, and wonder if we could remove timeout mechanism cleanly.

It would decrease failover times but I am not sure whether I've considered all SlotRequest exceptions without timeout mechanism are handled.

> 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.
