flink on k8s native 测试失败怎么办？

>
> 我这里在自己搭建的 k8s 测试环境中按照官网的 flink on k8s native
> 指南进行测试，然后一直报错，具体情况如下，请求大佬们的帮助，不胜感激。
>
> 一、环境
>
>     k8s  v1.18.16
>     flink  flink-1.12.2
>     java  openjdk version "11" 2018-09-25
>
> 二、官网规定的前提条件
>
>    1、Kubernetes >= 1.9  满足
>
>
>
>     2、权限检查  满足
>
>
>  3、启用 Kubernetes DNS  满足
>
>
> 4、default service account with RBAC
> <https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/resource-providers/native_kubernetes/#rbac> permissions
> to create, delete pods ，我这里创建新的 命名空间和账号，也是满足的，情况如下：
>
> kubectl create namespace flink-session-cluster
>
> kubectl create serviceaccount flink -n flink-session-cluster
>
> kubectl create clusterrolebinding flink-role-binding-flink \ --clusterrole
> =edit \ --serviceaccount=flink-session-cluster:flink
>
>
> 三、启动 session 并提交 flink 任务
>
>      3.1 启动session 命令
>
> ./bin/kubernetes-session.sh -Dkubernetes.cluster-id=my-first-flink-cluster
> \
> > -Dkubernetes.namespace=flink-session-cluster \
> > -Dkubernetes.jobmanager.service-account=flink \
> > -Dkubernetes.service.exposed.type=NodePort
>
>   日志：
>
>
>   3.2 提交flink 任务
>
>    命令：
>       ./bin/flink run \
> >     --target kubernetes-session \
> > -Dkubernetes.namespace=flink-session-cluster \
> >     -Dkubernetes.cluster-id=my-first-flink-cluster \
> > -Dkubernetes.jobmanager.service-account=flink \
> >     ./examples/streaming/TopSpeedWindowing.jar
>
>    报错日志如下：
>
> Executing TopSpeedWindowing example with default input data set.
> Use --input to specify file input.
> Printing result to stdout. Use --output to specify output path.
