本地local运行Spark程序报错 ERROR SparkContext:91 - Error initializing SparkContext

[lzw2016]

刚刚上手Spark，确保环境已经搭建成功了。scala版本是2.11.12，spark是2.4版本。使用eclipse安装了scala插件，然后创建了scala项目，导入了本地scala的jar包和spark目录下jars中的所有jar包，运行了个wordcount程序，如下：

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
import org.apache.spark.rdd.RDD

object HelloWorld {
  def main(args: Array[String]): Unit = {
    
    val conf = new SparkConf().setMaster("local").setAppName("WC")
    val sc = new SparkContext(conf)
    val rdd = sc.textFile("hello.txt",1)
    rdd.flatMap(_.split(" ")).map((_,1)).reduceByKey(_+_).foreach(println)
  }
}

报错信息如下：

想请教各位大佬，有没有遇见过这个问题？我确保环境什么的是没问题的，我写了个java的wordcount代码可以本地运行的。

看错误提示是初始化metrics.properties失败阿，conf目录下看看有没有这个文件，没有的话看看有没有metrics.properties.template, 复制一个试试
