Hbase启动从节点报错：FATAL org.apache.hadoop.hbase.regionserver.HRegionServer:...ClockOutOfSyncException

前提：

配置好hadoop、zookeeper，和Hbased的配置文件。

通过主节点启动Hbase： ./bin/start-hbase.sh

报错：

2016-08-17 11:29:40,895 FATAL org.apache.hadoop.hbase.regionserver.HRegionServer: Master rejected startup because 
clock is out of sync org.apache.hadoop.hbase.ClockOutOfSyncException: org.apache.hadoop.

2) 解决

明显看到报错信息：

Time difference of 43175940ms > max allowed of 180000ms

解决方案A：

<span style="font-size:18px;">同步集群主机的时间</span>
           

解决方案B：

配置hbase-site.xml  增加节点

<property>
       <name>hbase.master.maxclockskew</name>
       <value>180000</value>
       <description>Time difference of regionserver frommaster</description>
   </property>
           

发现已经配置了，可是为什么还报错 时间差 大于了 180000ms 呢？

速度查看系统的时间，分别为：

171 Wed Aug 17 23:36:33 CST 2016
172 Wed Aug 17 23:36:33 CST 2016
173 Wed Aug 17 23:36:33 EDT 2016
           

细心才发现，时间的格式不一致，一个为CST，一个为EDT，所以EDT的这台机器老报错。

解决：

# shell中直接执行：
mv /etc/localtime /etc/localtime.bak
ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime
date
           

重启Hbase，问题解决。
