Question

当我重新启动群集时，由于数据库检查失败，ambari没有启动：

sudo service ambari-server restart --skip-database-check
Using python  /usr/bin/python
Restarting ambari-server
Waiting for server stop...
Ambari Server stopped
Ambari Server running with administrator privileges.
Organizing resource files at /var/lib/ambari-server/resources...
Ambari Server is starting with the database consistency check skipped. Do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. See "/var/log/ambari-server/ambari-server-check-database.log" for more details on the consistency issues.
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.....................
DB configs consistency check failed. Run "ambari-server start --skip-database-check" to skip. You may try --auto-fix-database flag to attempt to fix issues automatically. If you use this "--skip-database-check" option, do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. See /var/log/ambari-server/ambari-server-check-database.log for more details on the consistency issues.
ERROR: Exiting with exit code -1.
REASON: Ambari Server java process has stopped. Please check the logs for more information.

我查看了＆＃34; /var/log/ambari-server/ambari-server-check-database.log"中的日志，我看到了：

2017-08-23 08:16:13,445  INFO - Checking Topology tables
2017-08-23 08:16:13,447 ERROR - Your topology request hierarchy is not complete for each row in topology_request should exist at least one raw in topology_logical_request, topology_host_request, topology_host_task, topology_logical_task.

我尝试了两个选项--auto-fix-database和--skip-database-check，它没有用。

似乎postgresql没有正确启动，即使在Ambari的日志中也没有提到postgresql没有启动或不可用，但ambari无法访问拓扑结构很奇怪存储在其中的配置。

sudo service postgresql restart
Stopping postgresql service:                               [  OK  ]
Starting postgresql service:                               [  OK  ]

它成功了：

sudo service ambari-server restart
Using python  /usr/bin/python
Restarting ambari-server
Ambari Server is not running
Ambari Server running with administrator privileges.
Organizing resource files at /var/lib/ambari-server/resources...

Ambari不会重启：数据库检查失败
