我已经在centos 7上安装了ambari server 2.2.0，使用了对ambari server安装程序的所有默认响应。
我没有添加新用户，也没有更改“admin”的默认密码。
我最初可以登录到ui，并使用restapi提交蓝图和集群。集群创建正确，所有安装的hadoop服务运行正常。堆栈是hdp2.3。
然而，几天后，我就不能再登录到ambari ui了。当我登陆登录页面并尝试以“admin”身份登录时，我看到以下消息：

Unable to connect to Ambari Server. Confirm Ambari Server is running and you can reach Ambari Server from this machine.

当我检查/var/log/ambari-server/ambari-server.log时，我看到以下堆栈跟踪：

我真的需要知道如何从中恢复过来。hadoop服务目前运行良好，但我需要用于管理\警报等的ambari ui。我希望不必重新创建集群，因为它已经在使用中。
编辑
我应该补充一点，我仍然能够直接使用postman或curl之类的应用程序发出restapi请求。例如：/api/v1/clusters/{name}在使用admin\admin作为身份验证时返回正确的信息。

我已经设法康复了，尽管我仍然不知道是什么导致了这个问题。
查看postgresql中的“user”表，“active\u widget\u layouts”列的值如下所示：

"[{"id":"8"},{"id":"9"},{"id":"10"}]"

但当我查看“widget\u layout”表时，表中最低的id是11。这就是在最初的帖子中引起npe的原因。在我将该字段中的3个值分别更改为11、12和13之后，我可以毫无问题地登录到ui。
再次，我不知道如何再现这个问题。我不知道发生了什么会导致这样的事情。但至少我能康复。
