Question

我正尝试使用Spark连接器和AAD包连接到Azure SQL，如下面的链接所述...

https://docs.microsoft.com/en-us/azure/sql-database/sql-database-spark-connector#connect-spark-to-azure-sql-database-using-aad-authentication

但是无论使用身份验证类型为“ ActiveDirectoryPassword”还是“ accessToken”，都会出现错误。

使用“ accessToken”，我得到“用户“ NT Authority \ Anonymous Logon”的登录失败。.并且使用“ ActiveDirectoryPassword”，我得到了类似的错误：（我能够成功运行import com.microsoft.aad .adal4j.AuthenticationException ...仍然没有运气。）

按照以下链接上的说明进行操作： https://docs.microsoft.com/en-us/azure/sql-database/sql-database-spark-connector#connect-spark-to-azure-sql-database-using-aad-authentication

遵循以下步骤来解决此问题：

旋转HDInsight群集并打开Jupyter UI
使用Spark内核为Scala命令创建新笔记本并在以下命令下运行：

%% configure -f {“ conf”： { “ spark.jars.packages”：“ com.microsoft.azure:azure-sqldb-spark:1.0.2,com.microsoft.azure:adal4j:1.6.3” } }
然后运行：

导入com.microsoft.azure.sqldb.spark.config.Config 导入com.microsoft.azure.sqldb.spark.connect._ 导入com.microsoft.aad.adal4j._ 导入com.microsoft.aad.adal4j.AuthenticationException
其次：

val config = Config（Map（ “ url”->“ xxxxx.database.windows.net”， “数据库名称”->“ db1”， “ dbtable”->“ dbo.BuildVersion”， “用户”->“ xyz@domain.com”， “密码”->“ xxxxxxxx”， “身份验证”->“ ActiveDirectoryPassword”， “ hostNameInCertificate”->“ * .database.windows.net”， “加密”->“真” ））
要阅读上表，请运行：

val collection = spark.read.sqlDB（config）

出现错误。

预期会获得表结果，但会出现异常。

无法使用AAD帐户通过Jupyter从Azure SQL读取
