org.apache.hadoop.hbase.ClockOutOfSyncException报错

Caused by: org.apache.hadoop.hbase.ipc.RemoteWithExtrasException(org.apache.hadoop.hbase.ClockOutOfSyncException): org.apache.hadoop.hbase.ClockOutOfSyncException: Server migu-cdn-hbase001.migu01.mmtrix.com,6201,1583991597027 has been rejected; Reported time is too far out of sync with master. Time difference of 142315ms > max allowed of 120000ms

重启hbase集群后， 有一个节点因为时间差距导致启动失败
产生原因： 节点之间的时间不同步

解决方案两种：
第一种 hbase的配置文件hbase-site.xml增加（一般不建议）：

<property>
        <name>hbase.master.maxclockskew</name>
        <value>150000</value>
</property>

第二种:
使用ntp同步时间。
