java - Apache Spark 启动时出错

Question

我想在 Apache Spark 中启用单集群，我安装了 java 和 scala。我下载了 Apache Hadoop 2.6 的 spark 并解压。我正在尝试打开 spark-shell 但抛出了一个错误，此外，我无权访问 sc in shell。我从源代码编译但同样的错误。我做错了什么？

刚刚开始学习Spark，希望以本地模式运行Spark。我遇到了像你这样的问题。问题:

java.net.BindException: Failed to bind to: /124.232.132.94:0: Service 'sparkDriver' failed after 16 retries!

因为我只是想在本地模式下运行Spark，所以我找到了解决这个问题的方案。解决方案:编辑文件 spark-env.sh(您可以在 $SPARK_HOME/conf/ 中找到它)并将其添加到文件中:

export  SPARK_MASTER_IP=127.0.0.1
export  SPARK_LOCAL_IP=127.0.0.1

之后，我的 Spark 在本地模式下工作正常。我希望这可以帮助你! :)
