如何在spark submit中将json格式作为一个参数传递？

spark-submit --class com.example.MyApp --master yarn --deploy-mode cluster myApp.jar --jsonParam '{"key1": "value1", "key2": "value2"}'

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
import com.fasterxml.jackson.databind.ObjectMapper

object MyApp {
  def main(args: Array[String]): Unit = {
    val jsonParam = args(0) // 获取传递的JSON参数
    val objectMapper = new ObjectMapper()
    val paramMap = objectMapper.readValue(jsonParam, classOf[Map[String, String]]) // 解析JSON参数为Map

    // 使用解析后的参数进行后续处理
    val key1 = paramMap("key1")
    val key2 = paramMap("key2")
    // ...
  }
}
