为什么数据在我的本地目录中不存在？ kubernetes-hadoop-cluster

Question

无论如何，即使清单显示了卷声明，并且PVC和PV似乎是正确设置的（至少据我所知），我在本地计算机上没有看到任何文件来管理HDFS Namenode格式。 （我只想将其格式化一次以拥有一个群集ID。）

我不确定我在做什么错或需要修复什么。 Namenode的hadoopDeployment：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: hadoop-namenode
  labels:
    app: hadoop
    role: namenode
spec:
  replicas: 1
  selector:
    matchLabels:
      app: hadoop
      role: namenode
  serviceName: "hadoop-namenode-service"
  template:
    metadata:
      labels:
        app: hadoop
        role: namenode
    spec:
      volumes:
        - name: hadoop-namenode-storage
          persistentVolumeClaim:
            claimName: hadoop-pvc-namenode
      containers:
      - name: namenode
        image: chrlrwork/hadoop-ubuntu-3.4.1:0.0.7
        ports:
        - containerPort: 9000
        - containerPort: 9870
        - containerPort: 9864
        volumeMounts:
        - mountPath: "/opt/hadoop/data/hdfs/"
          name: hadoop-namenode-storage
        resources:
          requests:
            memory: "1Gi"
            cpu: "500m"
          limits:
            memory: "1Gi"
            cpu: "500m"
        command:
          - "/bin/bash"
          - "/opt/hadoop/start-service.sh"

apiVersion: v1
kind: Service

PVC和PV表现：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: hadoop-pv-namenode
spec:
  storageClassName: manual
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  hostPath:
    path: "/mnt/hadoop/namenode"
    type: DirectoryOrCreate

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: hadoop-pvc-namenode
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

我不得不提到我给当地目录提供了所有可能的许可。 如果您有一个更好的主意去做我尝试的事情，我将很高兴阅读您！

提前感谢！！！

toter的想法要做我尝试的事情，我很高兴阅读

Yeah，我愿意，不是HDFS。 如何通过Helm图在Kubernetes安装Hadoop？
