使用ActiveDirectoryPassword连接Azure SQL DB时出错

Question

我正在尝试用AAD-Password-auth从Databricks连接Azure sql db。我导入了azure sql数据库

java.lang.NoClassDefFoundError: com/nimbusds/oauth2/sdk/AuthorizationGrant

已将nimbusds库导入我的工作区。

这里是配置

import com.microsoft.azure.sqldb.spark.config.Config
import com.microsoft.azure.sqldb.spark.connect._
import org.apache.spark.sql.SparkSession

val spark: SparkSession = SparkSession.builder().getOrCreate()

    val config = Config(Map(

      "url"            -> "ServerName.database.windows.net",
      "databaseName"   -> "dbname",
      "dbTable"        -> "dbo.test",
      "user"           -> "[e-mail]",
      "password"       -> "pwd",
      "authentication" -> "ActiveDirectoryPassword",
      "encrypt"        -> "true",
      "trustServerCertificate"->"false",
      "hostNameInCertificate"->"*.database.windows.net"
    ))

    val collection = spark.read.sqlDB(config)
    collection.show()

如果有人解决了这个问题，请帮助我。

已知工作配置-Databricks Runtime 5.2（包括ApacheSpark 2.4.0和Scala 2.11）

1. 导航到群集

已知的工作版本-com.microsoft.azure： azure-sqldb-火花： 1.0.2

更新变量值（CusterName，服务器，数据库，表，用户名，密码）

这将执行以下操作：

1. 在dbfs:/databricks/init/
2. 创建一个子文件夹，其名称为Databricks群集
3. 为每个依赖项创建bash脚本

Bash Script命令：*wget：从Web服务器检索内容*--退出：关闭wget的输出*-O：输出

依赖项：

>

http://central.maven.org/maven2/com/nimbusds/oauth2-oidc-sdk/5.24.1/oauth2-oidc-sdk-5.24.1.jar

这是执行init脚本所必需的。

这将测试通过Active Directory身份验证连接到Azure SQL数据库的能力。

初始化命令

// Initialisation
// This code block only needs to be run once to create the init script for the cluster (file remains on restart)

// Get the cluster name
var clusterName = dbutils.widgets.get("cluster")

// Create dbfs:/databricks/init/ if it doesn’t exist.
dbutils.fs.mkdirs("dbfs:/databricks/init/")

// Create a directory named (clusterName) using Databricks File System - DBFS.
dbutils.fs.mkdirs(s"dbfs:/databricks/init/$clusterName/")

// Create the adal4j script.

// Check that the cluster-specific init script exists.
display(dbutils.fs.ls(s"dbfs:/databricks/init/$clusterName/"))

测试命令

// Connect to Azure SQL Database via Active Directory Password Authentication
import com.microsoft.azure.sqldb.spark.config.Config
import com.microsoft.azure.sqldb.spark.connect._

// Get Widget Values
var server = dbutils.widgets.get("server")
var database = dbutils.widgets.get("database")
var table = dbutils.widgets.get("table")
var username = dbutils.widgets.get("user")
var password = dbutils.widgets.get("password")

val config = Config(Map(
  "url"                    -> s"$server.database.windows.net",
  "databaseName"           -> s"$database",

val collection = sqlContext.read.sqlDB(config)
collection.show()
