启动时Apache Spark错误

Question

我想在Apache Spark中启用单个集群,我安装了java和scala.我为Apache Hadoop 2.6下载了火花并解压缩.我试图转动spark-shell但是却抛出了一个错误,另外,我无法访问shell中的sc.我从源代码编译但是同样的错误.我究竟做错了什么？

我刚刚开始学习Spark,我希望在本地模式下运行Spark.我遇到了像你这样的问题.问题:

java.net.BindException:无法绑定到:/124.232.132.94:0:服务'sparkDriver'在16次重试后失败!

因为我只想在本地模式下运行Spark,所以我找到了解决这个问题的解决方案.解决方案:编辑文件spark-env.sh(您可以在您的文件中找到它$SPARK_HOME/conf/)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.我希望这可以帮到你!:)
