安装ambari报错 Cluster not found

具体报错内容如下:

Error message: The specified resource doesn't exist: Cluster not found, clusterId=2

看到这个报错,直接导致无法进行安装

期间尝试了重新安装,仍然不行

尝试了减少安装组件,仍然是这个报错

F12看报错内容,发现了问题

在点DEPLOY按钮时, 有3个调用

1. 持久化

http://172.16.20.21:8080/api/v1/clusters?_=1683594870288 无返回

2.集群

返回结果

{
  "href" : "http://172.16.20.21:8080/api/v1/clusters?_=1683594870288",
  "items" : [
    {
      "href" : "http://172.16.20.21:8080/api/v1/clusters/bigtest",
      "Clusters" : {
        "cluster_name" : "bigtest"
      }
    }
  ]
}

3. 获取集群信息, 就是这个接口报错

http://172.16.20.21:8080/api/v1/clusters/bigtest

结果: 这个错误是404错误,也即接口找不到, 确实是这样,我们才开始安装,怎么会有这个集群呢?

{
  "status" : 404,
  "message" : "The specified resource doesn't exist: Cluster not found, clusterId=2"
}

哪怕我换集群名,重新安装,仍然报这个错, 这说明系统认为这个集群已经存在了,而实际上并不存在

那么解决办法就简单了,清除此集群的所有数据,重新安装

按如下语句进行删除, 删除前备份数据库,如果出现问题时,方便还原数据库

select * from clusters c where cluster_id = 2


-- 7) 
delete from clusters where cluster_id = 2

select * from clusterstate where cluster_id = 2

-- 6) 
delete from clusterstate where cluster_id = 2


select * from clusterservices where cluster_id = 2

-- 5) 
delete from clusterservices where cluster_id = 2

select * from servicecomponentdesiredstate where cluster_id  = 2

-- 4) 
delete from servicecomponentdesiredstate where cluster_id  = 2


select * from servicedesiredstate where cluster_id  = 2

-- 3) 
delete from servicedesiredstate where cluster_id  = 2

select * from clusterconfig where cluster_id = 2

-- 2)
delete from clusterconfig where cluster_id = 2

select * from serviceconfigmapping a join clusterconfig b on a.config_id = b.config_id where b.cluster_id = 2

-- 1)
delete a from serviceconfigmapping a join clusterconfig b on a.config_id = b.config_id where b.cluster_id = 2

重启ambari服务

sudo ambari-server restart

即可解决问题
