problem description

When ambari opens kersei, create principals after stop services gives the following error:

Verify that the error is mycluster-112020@admin/admin@OCDP.COM This principal syntax is illegal

solutions

ambari will go to the database to get the principal name. Now this abnormal name causes an error, so delete the relevant records in the database.

These tables have foreign key checking, so turn off foreign key checking before deleting them, and restore them after deleting them.

--turn off foreign key checking show global variables like "%foreign_key_checks%";set global foreign_key_checks=0;show global variables like "%foreign_key_checks%";--delete keroros three tables error reported principldelete from keroros_keytab where keytab_path="/etc/security/keytabs/kerberos.service_check.112020.keytab";delete from keroros_principal where principal_name="mycluster-112020@admin/admin@ ODP.COM"; delete from keranthus_keytab_principal where keytab_path="/etc/security/keytabs/kerberos.service_check.112020.keytab";--restore foreign key checks set global foreign_key_checks=1;show global variables like "%foreign_key_checks%";
