>
> Key: FLINK-22802
> URL: https://issues.apache.org/jira/browse/FLINK-22802
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / Kubernetes
> Affects Versions: 1.13.0, 1.13.1, 1.12.4
> Environment: Kubernetes 1.19/1.20 provided as part of Openshift
> 4.6/4.7
> Flink 1.13.0 and 1.13.1-rc1
> Reporter: Enrique Lacal
> Assignee: Yang Wang
> Priority: Minor
> Labels: auto-deprioritized-major
> Fix For: 1.14.0
>
>
> Hi All,
> Currently, Flink is using version 4.9.2 of the Fabric8 Kubernetes Client
> which does not support new versions of the Kubernetes API such as 1.19 or
> 1.20 as pointed out by their [Compatibility
> Matrix|https://github.com/fabric8io/kubernetes-client#compatibility-matrix]
> which is support in 5.4.0 or above.
> As far as I have seen in the Flink documentation, Flink supports `Kubernetes
> >= 1.9.` but due to this dependency, it might not be the case. Is there a
> plan to update this dependency?
> What is the plan moving forwards when new versions of Kubernetes are released?
> I am raising this because I have been testing Flink HA Session Cluster on
> Kubernetes 1.19 and 1.20 and I have encountered some frequent errors that
> force the JM pods to restart or even result in an unrecoverable state.
> Thanks!
