• 使用该脚本注意事项

1. 安装hive之前确定机子有网络。或者yum 更改为本地源，因为会使用epel仓库下载一个pv的软件
2. 使用该脚本前提是自行安装好mysql数据库
3. 准备好tomcat软件包，该脚本使用tomcat9.x版本测试过能正常执行安装成功，其他版本没有测试过不知道有没这个问题
4. hive安装脚本中自动更换成tez引擎了，需要准备好tez安装软件，测试时使用的是tez-0.9.2版本
5. 安装之前请自行更改脚本内容前面定义的software_dir(所有安装软件包存放目录)、install_dir(安装软件目录)、mysql_user、mysql_password 这个几个变量根据自已情况进行更改
6. 使用该脚本之前需要把hadoop先安装好并且把hadoop集群启动起来，hadoop集群未启动切勿执行该脚本
