spark 3.1.1我试图使用带有&的 gradle 在 IntelliJ 中执行 scala 测试用例scala 2.12.13。但是 scala 测试因以下jackson-databind错误而失败。
val conf = new SparkConf().setMaster("local[2]")
val spark = SparkSession
.builder()
.config(conf)
.appName("Scala Test Cases")
.getOrCreate()
spark.sparkContext.setLogLevel("ERROR")
import spark.implicits._
Error initializing SparkContext.

我正在导入scalatest& holdenkarauin build.gradle：
testImplementation("org.scalatest:scalatest_2.12:3.0.4") {
exclude group: 'com.fasterxml.jackson.core', module: 'jackson-databind'
}
testImplementation("com.holdenkarau:spark-testing-base_2.12:3.0.1_1.1.0"){
exclude group: 'org.apache.xbean', module: 'xbean-asm6'
}
这些测试在使用spark 2.4.7&scala 2.11.12与以下依赖版本时运行良好。
testCompile("org.scalatest:scalatest_2.11:3.0.4")
testCompile("com.holdenkarau:spark-testing-base_2.11:2.4.5_0.14.0"){
exclude group: 'org.apache.xbean', module: 'xbean-asm6'
}
不知道我在这里错过了什么。我尝试强制更新杰克逊库，但仍然没有解决问题。
