hadoop集群算PI值出现current time is .... found ....

出现此错误,原因是主从节点的时间不同步导致的
解决方法就是配置时间同步,在终端切换为root用户
配置时钟需要虚拟机联网,如果修改为静态ip是不能联网的,解决方法

1.配置自动时钟同步
输入命令:crontab -e
出现一个窗口后按i使其进入插入模式,插入如下内容
0 1 * * * /usr/sbin/ntpdate us.pool.ntp.org
按ESC键后,输入冒号wq回车 即:wq
2.手动配置时钟同步
输入命令 ntpdate us.pool.ntp.org
同样的方式在其他节点上进行配置
