一、简介
Kudu是Cloudera开源的分布式列式存储引擎，支持分区、随机读写、批量扫描、实时更新等。可以通过Python API、Java API、Spark API、SQL(如Spark SQL、Impala)等读写Kudu。
二、准备
1、节点分配
kudu171 tserver
kudu172 master tserver
kudu177 master tserver
kudu190 master tserver
kudu209 tserver
2、下载安装包
首先下载需要安装的rpm包，有六个，下载五个就OK。
这里强调下应该注意版本信息，之前就因为系统是centos6。下载的却是centos7的安装包，导致出现一系列的依赖和升级问题层出不穷，最后又只好卸载重装。
下载链接如下：链接标题
下载的包如下：
kudu-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
kudu-client0-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
kudu-client-devel-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
kudu-master-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
kudu-tserver-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
3、进行安装
rpm安装包最好统一放置在机器的同一个目录下：/home/xxxxxx/kudu
所有节点都安装全部下载好的安装包，再去启动相应服务，省去麻烦
代码# yum localinstall kudu-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm kudu-client0-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm kudu-client-devel-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm kudu-master-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm kudu-tserver-1.9.0+cdh6.2.0-967373.el6.x86_64.rpm
这样安装可以解决部分依赖问题，如果还有问题就试一试再在后面加上--nodeps;(--nodeps 如果该RPM包的安装依赖其它包，即使其它包没装，也强迫安装。）
master节点测试下能不能单独启动
代码# service kudu-master start
三、配置

http:/kudu172:8051/masters
2、查看所有tservers
http:/kudu172:8051/tservers
若无法访问自行查看日志以及防火墙规则
