Chenya Zhang commented on YUNIKORN-704: --------------------------------------- [~Huang Ting Yao] thanks a lot! pls let us know if u need any help. Our team is waiting to include this PR fix for 2 weeks. ^ _ ^ > [Umbrella] Use the same mechanism to schedule daemon set pods as the default > scheduler > -------------------------------------------------------------------------------------- > > Key: YUNIKORN-704 > URL: https://issues.apache.org/jira/browse/YUNIKORN-704 > Project: Apache YuniKorn > Issue Type: Improvement > Components: shim - kubernetes > Reporter: Chaoran Yu > Assignee: Ting Yao,Huang > Priority: Blocker > Fix For: 1.0.0 > > Attachments: fluent-bit-describe.yaml, fluent-bit.yaml > > > We sometimes see DaemonSet pods fail to be scheduled. Please see attached > files for the YAML and _kubectl describe_ output of one such pod. We > originally suspected [node > reservation|https://github.com/apache/incubator-yunikorn-core/blob/v0.10.0/pkg/scheduler/context.go#L41] > was to blame. But even after setting the DISABLE_RESERVATION environment > variable to true, we still see such scheduling failures. The issue is > especially severe when K8s nodes have disk pressure that causes lots of pods > to be evicted. Newly created pods will stay in pending forever. We have to > temporarily uninstall YuniKorn and let the default scheduler do the > scheduling for these pods. > This issue is critical because lots of important pods belong to a DaemonSet, > such as Fluent Bit, a common logging solution. This is probably the last > remaining roadblock for us to have the confidence to have YuniKorn entirely > replace the default scheduler. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@yunikorn.apache.org For additional commands, e-mail: issues-h...@yunikorn.apache.org
