第4章 集成 Spark

4.1 环境准备

4.1.1 安装Spark

4.1.2 启动Hadoop（略）

4.2 spark-shell 方式

4.2.1 启动 spark-shell

1）启动命令

>   --conf 'spark.serializer=org.apache.spark.serializer.KryoSerializer' \
>   --conf 'spark.sql.catalog.spark_catalog=org.apache.spark.sql.hudi.catalog.HoodieCatalog' \
>   --conf 'spark.sql.extensions=org.apache.spark.sql.hudi.HoodieSparkSessionExtension'Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

4.2.7 删除数据

3.2.6 删除策略

1）逻辑删：将 value 字段全部标记为 null。

2）物理删：

（1）通过 OPERATION_OPT_KEY  删除所有的输入记录

（2）配置 PAYLOAD_CLASS_OPT_KEY = org.apache.hudi.EmptyHoodieRecordPayload 删除所有的输入记录

（3）在输入记录添加字段：_hoodie_is_deleted

4.2.8 覆盖数据
