将 Delta Lake 与 Amazon EMR on EKS 结合使用

将 Delta Lake 与 Amazon EMR on EKS 应用程序结合使用

1. 启动任务运行以在应用程序配置中提交 Spark 任务时，请包含 Delta Lake JAR 文件：

   --job-driver '{"sparkSubmitJobDriver" : {
         "sparkSubmitParameters" : "--jars local:///usr/share/aws/delta/lib/delta-core.jar,local:///usr/share/aws/delta/lib/delta-storage.jar,local:///usr/share/aws/delta/lib/delta-storage-s3-dynamodb.jar"}}'

2. 请包含 Delta Lake 额外配置，并使用 Amazon Glue Data Catalog 作为元存储。

   --configuration-overrides '{
           "applicationConfiguration": [
           {
             "classification" : "spark-defaults", 
             "properties" : {
               "spark.sql.extensions" : "io.delta.sql.DeltaSparkSessionExtension", 
               "spark.sql.catalog.spark_catalog":"org.apache.spark.sql.delta.catalog.DeltaCatalog",
   "spark.hadoop.hive.metastore.client.factory.class":"com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory" 
              }
           }]}'
