步骤1：下载 http://spark.apache.org/downloads.html
解压tar -zxvf spark-2.4.5-bin-hadoop2.7.tgz -C /usr/local
步骤2：配置环境变量 sudo vim /etc/profile
export SPARK_HOME=/usr/local/spark-2.4.5-bin-hadoop2.7
export PATH=$SPARK_HOME/bin:$PATH
刷新环境变量 source /etc/profile
步骤3：Local模式启动
Local 模式是最简单的一种运行方式，它采用单节点多线程方式运行，不用部署，开箱即用，适合日常测试开发。
local：只启动一个工作线程；
local[k]：启动 k 个工作线程；
local[*]：启动跟 cpu 数目相同的工作线程数。
直接执行命令 spark-shell --master local[2]
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
