环境信息

  1. 操作系统:macOS Mojave 10.14.6
  2. 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

  1. 安装scala:
代码语言:javascript复制
brew install scala
  1. 配置scala的环境变量,打开文件~/.bash_profile,增加以下配置内容:
代码语言:javascript复制
export SCALA_HOME=/usr/local/Cellar/scala/2.13.0
export PATH=$PATH:$SCALA_HOME/bin
  1. 执行命令source ~/.bash_profile,再验证scala:
代码语言:javascript复制
base) zhaoqindeMBP:~ zhaoqin$ scala -version
Scala code runner version 2.13.0 -- Copyright 2002-2019, LAMP/EPFL and Lightbend, Inc.
  1. 下载spark,地址是:http://spark.apache.org/downloads.html ,如下图红框:
  1. 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
  2. 配置spark的环境变量,打开文件~/.bash_profile,增加以下配置内容:
代码语言:javascript复制
export SPARK_HOME=/usr/local/spark
export PATH=$PATH:$SPARK_HOME/bin
  1. 执行命令source ~/.bash_profile使配置生效;
  2. 打开文件spark/conf/spark-env.sh,在尾部增加以下三行:
代码语言:javascript复制
export SCALA_HOME=/usr/local/Cellar/scala/2.13.0
export SPARK_MASTER_IP=localhost
export SPARK_WORKER_MEMORY=2G
  1. 确保hdfs和yarn已经启动,然后执行命令spark-shell,即可启动spark服务:
