java - 如何修复 java.lang.UnsatisfiedLinkError: no mssql-jdbc_auth-9.2.1.x64 in java.library.path Pyspark 错误

Question

我正在运行 Pyspark 应用程序，它使用 Windows 身份验证连接到 SQL 服务器。这是代码。jar 和 dll 文件在我调用 Pyspark shell 的 PATH 上都可用。以下是JAVA版本-

$ java -version
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

请原谅我对 Java 的理解非常有限。此错误是否意味着与 SQL 服务器的连接成功并且在从表中获取数据时失败，或者是因为我使用了错误版本的 dll 文件（x64 与 x86）甚至连接不成功？我该如何解决这个问题？
