Sql server 无法使用spark\u read\u jdbc连接SQL Server和SparkyR

我正在尝试使用library（SparkyR）与SQL Server建立连接，以便使用R Studio从计算机上的本地数据库中提取数据。最后，我要做的是使用spark进行查询进行计算。请参见syntaxis以供参考：

library(sparklyr)

#Configuration
config <- spark_config()

# SQL Server JBDC Driver for setting purposes
config$`sparklyr.shell.driver-class-path` <- 
  "C:/Program Files/Java/Microsoft JDBC Driver 7.2 for SQL Server/sqljdbc_7.2/enu/mssql-jdbc-7.2.1.jre8.jar"

# Connection to Spark
sc <- spark_connect(master = "local", config = config)

# Want to connect to dbo.Activos
spark_read_jdbc(sc, "person_jdbc",  options = list(
  url = "jdbc:sqlserver://PORT-JBERROCAL/SQLEXPRESS:1433;integratedSecurity=true;",
  user = "root", password = "<password>",
  dbtable = "Activos"))

库（年）
#配置
我也有同样的问题，你解决过吗？我的朋友还没有。如果您有解决方法或潜在解决方案，请与他人分享！=）你得到答案了吗？
