复制了，我按照您说的集群管理–>新建集群–>导入主机，现在报一个新的错误：
[30130]install filebeat on host failed precheck join em cluster em-prod failed, exit status 1.
detail info: tiup is checking updates for component em …
A new version of em is available:
The latest version: v1.0.2
Local installed version:
Update current component: tiup update em
Update all components: tiup update --all
The component em version is not installed; downloading from repository.
Starting component em: /home/hadoop/.em/components/em/v1.0.2/tiup-em /home/hadoop/.em/components/em/v1.0.2/tiup-em display em-prod --json --wait-timeout 360 --yes
Error: em cluster em-prod not exists
Verbose debug logs has been written to /home/hadoop/.em/logs/tiup-cluster-debug-2022-09-05-18-06-29.log.
但是这个集群是绝对存在的，我部署完TiUniManager，就创建了集群em-prod，不然怎么会有后续的操作呢
