Subject [jira] [Commented] (FLINK-8174) Mesos RM unable to accept offers for unreserved resources
Date Thu, 30 Nov 2017 20:23:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16273345#comment-16273345

Eron Wright  commented on FLINK-8174:

We're working on a fix that will allow Flink to use both unreserved and reserved resources.
  If we cannot solve it soon, I would suggest reverting the earlier fix so that unreserved
resources work as they did before.  I'll send another update to the dev list later.

>                 URL: https://issues.apache.org/jira/browse/FLINK-8174
>             Project: Flink
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.4.0, 1.3.3
>            Reporter: Eron Wright 
>            Assignee: Eron Wright 
>            Priority: Blocker
>             Fix For: 1.4.0
> Flink has suffered a regression due to FLINK-7294.   Any attempt to accept a resource
offer that is based on unreserved resources will fail, because Flink (as of FLINK-7294) erroneously
insists that the resource come from a prior reservation.
> Looking at the original issue, the problem may have been misdiagnosed.  Ideally Flink
should work with both reserved and unreserved resources, but the latter is a more common situation
that is now broken.
