Mac部署spark2.4.4 - HelloWorld开发者社区

环境信息

操作系统：macOS Mojave 10.14.6
JDK：1.8.0_211 (安装位置：/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home)

前提条件

请参考《Mac部署hadoop3(伪分布式)》一文，在Mac上事先部署好hadoop3

部署步骤

安装scala：

brew install scala
配置scala的环境变量，打开文件~/.bash_profile，增加以下配置内容：

export SCALA_HOME=/usr/local/Cellar/scala/2.13.0 export PATH=$PATH:$SCALA_HOME/bin
执行命令source ~/.bash_profile，再验证scala：

base) zhaoqindeMBP:~ zhaoqin$ scala -version Scala code runner version 2.13.0 -- Copyright 2002-2019, LAMP/EPFL and Lightbend, Inc.
下载spark，地址是：http://spark.apache.org/downloads.html ，如下图红框：
将下载的文件在/usr/local/目录下解压，并将文件夹名字从spark-2.4.4-bin-hadoop2.7改为spark
配置spark的环境变量，打开文件~/.bash_profile，增加以下配置内容：

export SPARK_HOME=/usr/local/spark export PATH=$PATH:$SPARK_HOME/bin
执行命令source ~/.bash_profile使配置生效；
打开文件spark/conf/spark-env.sh，在尾部增加以下三行：

export SCALA_HOME=/usr/local/Cellar/scala/2.13.0 export SPARK_MASTER_IP=localhost export SPARK_WORKER_MEMORY=2G
确保hdfs和yarn已经启动，然后执行命令spark-shell，即可启动spark服务：
