namenode,datanode时间不同步问题
解决方法
方法一：
1.重新启动，重新执行
方法二： 我用了第二种方法
如果提示西面的提示
[root@Slave2 mapreduce]# ntpdate pool.ntp.org -bash: ntpdate: command not found
需要下载 yum install -y ntp
2. 多个datanode与namenode进行时间同步，在每台服务器执行如下两个命令进行同步
1）输入“cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime”
2）输入“ntpdate pool.ntp.org” 或者是 ntpdate s2c.time.edu.cn
方法三：
#crontab -e
编辑：
0 1 * * * /usr/sbin/ntpdate cn.pool.ntp.org
wq保存
#/usr/sbin/ntpdate cn.pool.ntp.org
报错：……the NTP socket is in use, exiting
（停止服务）
# service ntpd stop
（设置开机不启动）
# chkconfig ntpd off
然后执行：
# /usr/sbin/ntpdate cn.pool.ntp.org
成功：
adjust time server 5.79.108.34 offset -0.001357 sec
即时生效暴力方法：
# date -s 00:00:00
