kudu安装过程中可能出现的问题

kudu安装过成中可能出现的问题

1、给用户添加sudo权限的时候报错

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

2、启动kudu的时候报错

Failed to start Kudu Master Server. Return value: 1 [FAILED]
去日志文件中查看:
错误:F0810 09:04:08.354552 4866 master_main.cc:68] Check failed: _s.ok() Bad status:
Service unavailable: Cannot initialize clock: Error reading clock. Clock considered
unsynchronized
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

3、启动过程中报错

F0810 21:31:12.620932 20143 master_main.cc:71] Check failed: _s.ok() Bad status:
Invalid argument: Unable to initialize catalog manager: Failed to initialize sys tables
async: on-disk master list
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/*

4、启动过程中报错

F0913 15:12:00.628237 20859 master_main.cc:74] Check failed: _s.ok() Bad status: IO
error: Could not create new FS layout: unable to create file system roots: unable to
write instance metadata: Call to mkstemp() failed on name template
/export/servers/kudu/master/instance.kudutmp.XXXXXX: Permission denied (error 13)
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
