小编给大家分享一下Hadoop多节点测试环境快速部署半自动脚本的示例代码，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
本半自动部署包括两个脚本hdp_ini.sh（环境初始化）和 hdp_bld.sh（创建hadoop）。
执行完第一个脚本，再检查手动调整一下。
然后根据第二个脚本里说明配置好ssh passwordless, 再执行第二个脚本，基本上就可以快速的部署好测试环境。
hdp_ini.sh - Run on all the nodes in your cluster env!
#!/bin/bash
# Name: hdp_ini.sh
# Purpose: For Fast INITIALIZATION of the testing env, to save time for life :)
# Author: Stone@dbinterest.com + Many guys on the internet
# Time: 03/09/2012
# User: root
# Reminder: 1) Remember to add the executable permission the script before start the script
# eg: chmod a+x env_ini.bash OR chmod 744 env_ini.bash
# 2) Need to change the $HOSTNAME2BE and $HOST_IP variable on each node accordingly.
# Attention: 1) You might need run this script TWICE to have the server ip address in effect
# if the ifconfig output shows deivce other than "eth0"!!!
# 2) Please execute the script from the console inside the node, not form ssh tool
# like xshell, SecureCRT, etc. to avoid connection lost.
