scala - 异常 : ERROR SparkContext - Error initializing local SparkContext. java.net.BindException

Question

我正在尝试为 spark 应用程序编写测试，但在尝试运行下一个测试时出现此异常

     class BasicIT {

      val sparkConf: SparkConf = new SparkConf().setAppName("basic.phase.it").setMaster("local[1]")
      var context:SparkContext = new SparkContext(sparkConf)
    @Test
    def myTest(): Unit = {
      print("test")
     }
    }

失败并出现此异常:

目前在 OS x Yosemite 上使用 IntelliJ。

我做错了什么？用于工作的相同代码..

尝试使用将 SPARK_LOCAL_IP="127.0.0.1"导出到 load-spark-env.sh 或在运行 spark 应用程序之前设置 SPARK_LOCAL_IP="127.0.0.1"。它对我有用。
