kudu安装过程中可能出现的问题

sudo: /etc/sudoers is world writable
解决方式：pkexec chmod 555 /etc/sudoers

Failed to start Kudu Master Server. Return value: 1 [FAILED]
去日志文件中查看：

Service unavailable: Cannot initialize clock: Error reading clock. Clock considered

解决：
第一步：首先检查是否有安装ntp：如果没有安装则使用以下命令安装：
yum -y install ntp
第二步：设置随机启动：
service ntpd start
chkconfig ntpd on

Invalid argument: Unable to initialize catalog manager: Failed to initialize sys tables

解决：
（1）：停掉master和tserver
（2）：删除掉之前所有的/export/servers/kudu/master/*和/export/servers/kudu/tserver/*

这是因为kudu默认使用kudu权限进行执行，可能遇到文件夹的权限不一致情况，更改文件夹权限即可
