泪目！一天终于解决了这个bug Pyspark: Exception: Java gateway process exited before sending the driver its port

我参考​​使用 Docker 快速部署 Spark + Hadoop 大数据集群 - 知乎​​

       Bug：

        里面的compose拉齐集群，但是出现一个致命的bug，普通用户，我下载不了pip所有包，包括jupyter，用exec -u 0 -it进去的root用户可以下载，但是却启动不了pyspark集群，会报

​​Pyspark: Exception: Java gateway process exited before sending the driver its port number​​

bug

解决bug在compose加上user：root

 完成的docker-compose

version: '2'

services:
  spark:
    image: docker.io/bitnami/spark:3
    hostname: master
    user: root
    environment:
      - SPARK_MODE=master
      - SPARK_RPC_AUTHENTICATION_ENABLED=no
      - SPARK_RPC_ENCRYPTION_ENABLED=no
      - SPARK_LOCAL_STORAGE_ENCRYPTION_ENABLED=no
      - SPARK_SSL_ENABLED=no
    volumes:
      - ./:/opt/share
    ports:
      - '8080:8080'
      - '4040:4040'
  spark-worker-1:
    image: docker.io/bitnami/spark:3
    hostname: worker1
    user: root
    environment:
      - SPARK_MODE=worker
      - SPARK_MASTER_URL=spark://master:7077
      - SPARK_WORKER_MEMORY=1G
      - SPARK_WORKER_CORES=1
      - SPARK_RPC_AUTHENTICATION_ENABLED=no
      - SPARK_RPC_ENCRYPTION_ENABLED=no
      - SPARK_LOCAL_STORAGE_ENCRYPTION_ENABLED=no
      - SPARK_SSL_ENABLED=no
    volumes:
      - ./:/opt/share
    ports:
      - '8081:8081'
  spark-worker-2:
    image: docker.io/bitnami/spark:3
    hostname: worker2
    user: root
    environment:
      - SPARK_MODE=worker
      - SPARK_MASTER_URL=spark://master:7077

      - SPARK_RPC_ENCRYPTION_ENABLED=no
      - SPARK_LOCAL_STORAGE_ENCRYPTION_ENABLED=no
      - SPARK_SSL_ENABLED=no
    volumes:
      - ./:/opt/share
    ports:

终于实现我想实现的效果
