我在docker上运行hadoop，使用docker hub的apache/hadoop镜像。
我只是运行与默认配置和添加2模式datanode
在这里我的码头-组成。yaml

version: "2"
services:
   namenode:
      image: apache/hadoop:3.3.6
      hostname: namenode0
      command: ["hdfs", "namenode"]
      ports:
        - 9870:9870
      env_file:
        - ./config
      environment:
          ENSURE_NAMENODE_DIR: "/tmp/hadoop-root/dfs/name"
   datanode-0:
      image: apache/hadoop:3.3.6
      command: ["hdfs", "datanode"]
      env_file:
        - ./config
   datanode-1:
      image: apache/hadoop:3.3.6
      command: ["hdfs", "datanode"]
      env_file:
        - ./config
   datanode-2:
      image: apache/hadoop:3.3.6
      command: ["hdfs", "datanode"]
      env_file:
        - ./config
   resourcemanager:
      image: apache/hadoop:3.3.6
      hostname: resourcemanager
      command: ["yarn", "resourcemanager"]
      ports:
         - 8088:8088
      env_file:
        - ./config
      volumes:
        - ./test.sh:/opt/test.sh
   nodemanager:
      image: apache/hadoop:3.3.6
      command: ["yarn", "nodemanager"]
      env_file:
        - ./config

但在namenode UI中有3个活动节点x1c 0d1x
如果运行这个

$ hdfs dfsadmin -report

但是在yarn和资源管理器中只有一个节点active

$ yarn node -list

如何将其他节点添加到主动节点？
