解决启动ambari遇到Unable to determine server PID. Retrying... ......

我在启动ambari平台是遇到了问题：

[root@master ~]# ambari-server restart
Using python  /usr/bin/python
Starting ambari-server
Ambari Server running with administrator privileges.
Organizing resource files at /var/lib/ambari-server/resources...
Ambari database consistency check started...
Server PID at: /var/run/ambari-server/ambari-server.pid
Server out at: /var/log/ambari-server/ambari-server.out
Server log at: /var/log/ambari-server/ambari-server.log
Waiting for server start.........Unable to determine server PID. retrying...
......Unable to determine server PID. retrying...
......Unable to determine server PID. retrying...
ERROR: Exiting with exit code -1. 
REASON: Ambari Server java process died with exitcode 1. Check /var/log/ambari-server/ambari-server.out for more @R_612_4045@ion.

错误：退出并退出代码-1。原因：Ambari Server java进程因exitcode 1而死亡。检查/var/log/ambari-server/ambari-server.out以获取更多信息。
这个方法解决了我的问题，也希望能给你们一些帮助。
解决方法：
导入MysqL脚本

1. MysqL -uroot -pbigdata

2. MysqL> use ambari; MysqL> source
   /var/lib/ambari-server/resources/Ambari-DDL-MysqL-CREATE.sql;

但是我之前已经导入过脚本，不知道是哪里出现了问题，下面是我的过程

[root@master ~]# MysqL -uroot -pbigdata
