补充：关于 Kubernetes 部署 hadoop 方法

部署 Kubernetes 的集群：

sudo /home/sealer/sealer2/_output/bin/sealer/linux_amd64/sealer run docker.io/sealerio/kubernetes:v1.22.15 --masters 10.0.0.245 --nodes 10.0.0.246,10.0.0.247  --user sealer --passwd ********

Hadoop镜像，到docker hub上拉取：

docker pull kubeguide/hadoop:latest

编辑 hadoop.yaml 文件：

这个yaml文件包含一个ConfigMap，5个Service，8个pod，这里需要注意的是ConfigMap中HDFS_MASTER_SERVICE和HDOOP_YARN_MASTER不要使用IP，使用HDFS service的名称，否则datanode将会连接不上namenode，出现错误【ipc.Client: Retrying connect to server: xxx:9000.】

创建命令：

kubectl create -f hadoop.yaml
