配置 Iceberg 数据抽取节点

• 下载 Apache Hadoop
• 修改 jobmanager.sh 和 taskmanager.sh，加入 Hadoop 环境变量。启动命令可以参考 Apache Flink

export HADOOP_CLASSPATH=`$HADOOP_HOME/bin/hadoop classpath`

• 修改 docker/docker-compose 目录下的 docker-compose.yml，将 Hadoop 和 Flink 启动命令 挂载至容器中:

  jobmanager:
    image: apache/flink:1.13-scala_2.11
    container_name: jobmanager
    user: root
    environment:
      - |
        FLINK_PROPERTIES=
        jobmanager.rpc.address: jobmanager
    volumes:
      # Mount Hadoop
      - HADOOP_HOME:HADOOP_HOME
      # Mount the modified jobmanager.sh which adds the HADOOP_HOME env correctly
      - /jobmanager.sh:/opt/flink/bin/jobmanager.sh
    ports:
      - "8081:8081"
    command: jobmanager
  taskmanager:
    image: apache/flink:1.13-scala_2.11
    container_name: taskmanager
    environment:
      - |
        FLINK_PROPERTIES=
        jobmanager.rpc.address: jobmanager
        taskmanager.numberOfTaskSlots: 2
    volumes:
      # Mount Hadoop
      - HADOOP_HOME:HADOOP_HOME
      # Mount the modified taskmanager.sh which adds the HADOOP_HOME env correctly
      - /taskmanager.sh:/opt/flink/bin/taskmanager.sh
    command: taskmanager

Flink SQL API

使用 Flink sql client 之前，sql-client.sh 启动命令也需要添加 Hadoop 环境变量，并挂载至容器。 启动命令可以参考 Apache Flink

export HADOOP_CLASSPATH=`$HADOOP_HOME/bin/hadoop classpath`

使用 Flink sql cli：

CREATE TABLE `iceberg_table_source`(
    PRIMARY KEY (`_id`) NOT ENFORCED,
    `_id` STRING,
    `id` INT,
    `name` STRING,
    `age` INT)
    WITH (
    'connector' = 'iceberg-inlong',
    'catalog-database' = 'DATABASES',
    'catalog-table' = 'TABLE',
    'catalog-type' = 'HIVE',
    'catalog-name' = 'HIVE',
    'streaming' = 'true',
    'uri' = 'thrift://127.0.0.1:9083'
);
