# 验证

1. 组件安装可参考官方网站手册。安装方式分为单节点安装(https://hadoop.apache.org/docs/r3.1.1/hadoop-project-dist/hadoop-common/SingleCluster.html)和集群安装(https://hadoop.apache.org/docs/r3.1.1/hadoop-project-dist/hadoop-common/ClusterSetup.html)两种。
2. 使用Hadoop自带测试程序计算PI值。
  1 ./hadoop-3.1.1/bin/yarn jar hadoop-3.1.1/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.1.jar pi 5 10
