## 本地运行Spark方法
- 下载spark安装包
- 解压spark安装包
- 进入spark解压目录下，运行：
```bash
$ bin/spark-shell
```
- 在命令行提示符下拷贝以下代码并查看执行结果
```scala
import scala.math.random
val tasks = 10
val n = tasks * 100000
val count = sc.parallelize(1 until n, tasks).map { i =>
val x = random * 2 - 1
val y = random * 2 - 1
if (x*x + y*y <= 1) 1 else 0
}.reduce(_ + _)
println("Pi is roughly " + 4.0 * count / n )
```
## 分布式运行Spark方法
### 搭建hadoop集群
Hadoop YARN/HDFS配置文件参考：conf/hadoop目录
### 配置Spark客户端，并启动spark history server
- Spark客户端配置文件参考：conf/spark目录
- 启动spark history server: sbin/start-history-server.sh
### 将spark-shell运行在yarn client或cluster模式
- yarn client模式：bin/spark-shell --master yarn --deploy-mode client
- yarn cluster：bin/spark-shell --master yarn --deploy-mode cluster
