ambari 管理的hadoop cluster 的狀態都是存放在databases，透過ambari-server update db內的tables來確認狀態。
ambari 的 pssql 的 databases 為 "ambari" 預設帳號密碼為 ambari-server / bigdata
可以使用 psql -U ambari-server ambari
去連線查看當前的tables 狀態。

Hi Su,
The "ambari" database has a schema called "ambari". This is accessible by
the user "ambari-server".
1. Connect to the "ambari" database with "ambari-server": psql -U
ambari-server ambari (the default password is "bigdata")
2. Once you are in the psql prompt, you can list all the tables with: \dt
ambari.*
3. You can query tables like this: select * from ambari.clusters;
Hope this helps.
