Scala - 3.18 Spark - 3.5.0 Hadoop - 3.3.6
安装hadoop
从这里下载相应版本的hadoop下载后解压配置系统环境变量 sudo vim /etc/profile添加以下两行
export HADOOP_HOME/Users/collinsliu/hadoop-3.3.6/
export PATH$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin请自行替换位置 然后执行并生效系统环境变量 source /etc/profile安装Spark
从这里下载相应版本的Spark下载后解压同时类似于hadoop配置系统环境变量 sudo vim /etc/profile添加以下两行
export SPARK_HOME/Users/collinsliu/spark-3.5.0
export PATH$PATH:$SPARK_HOME/bin请自行替换位置 然后执行并生效系统环境变量 source /etc/profile然后配置spark连接hadoop形成local模式 a. 首先进入conf文件夹 cd /Users/collinsliu/spark-3.5.0/confb. 其次替换配置文件 cp spark-env.sh.template spark-env.shvim spark-env.shc. 添加以下三条连接使得spark能够找到对应的hadoop和相应的包
export JAVA_HOME/Library/Java/JavaVirtualMachines/jdk1.8.0_311.jdk/Contents/Home
export HADOOP_CONF_DIR/Users/collinsliu/hadoop-3.3.6/etc/hadoop
export SPARK_DIST_CLASSPATH$(/Users/collinsliu/hadoop-3.3.6/bin/hadoop classpath)测试安装成功
使用内置命令测试 cd /Users/collinsliu/spark-3.5.0/./run-example SparkPi可以看到很多输出最后找到
