Hi@arunek95,yes.But you gave me the idea. After I deleted the alert_current and alert_history tables data, the problem was solved.I don't know why, you know? And thank you very muchPREVIEW

arunek95 · Answer

Hi @luobo2019 , Can you please try the below 2 things and let me know how it goes -

Resolution 1 -

Step 1: cat /etc/ambari-server/conf/ambari.properties | grep ambari-server.user.

Know the user from above command.

Step 2: change user /var/run/ambari-server

chown -R <output of above command> /var/run/ambari-server

Resolution 2 - Take Ambari DB backup

1. Query the ambari.alert_current and ambari.alert_history tables, look at the 'definition_id' and 'alert_definition' columns in these tables.

2. Look at the alert_definitions table

select definition_id from ambari.alert_definition;

and check the definition IDs.

3. Look for any definition IDs referenced in the alert_current and alert_history tables that are not present in alert_definition.

4. In ambari.alert_current, remove any row that references a definition ID that is not present in alert_definition

5. In ambari.alert_history, remove any row that references a definition ID that is not present in alert_definition
