### What changes were proposed in this pull request? This PR aims to upgrade `kubernetes-client` library to bring the JDK8 related fixes. Please note that JDK11 works fine without any problem. - https://github.com/fabric8io/kubernetes-client/releases/tag/v4.9.2 - JDK8 always uses http/1.1 protocol (Prevent OkHttp from wrongly enabling http/2) ### Why are the changes needed? OkHttp "wrongly" detects the Platform as Jdk9Platform on JDK 8u251. - https://github.com/fabric8io/kubernetes-client/issues/2212 - https://stackoverflow.com/questions/61565751/why-am-i-not-able-to-run-sparkpi-example-on-a-kubernetes-k8s-cluster Although there is a workaround `export HTTP2_DISABLE=true` and `Downgrade JDK or K8s`, we had better avoid this problematic situation. ### Does this PR introduce _any_ user-facing change? No. This will recover the failures on JDK 8u252. ### How was this patch tested? - [ ] Pass the Jenkins UT - [ ] Pass the Jenkins K8S IT with the K8s 1.13 - [ ] Manual testing with K8s 1.17.3. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
