The error messages indicate that there are issues with the MySQL database during the installation of Cloudera Manager.
The first error message suggests that the password for the MySQL user does not meet the current policy requirements, which could be related to password complexity or length.
The second error message indicates that a database with the same name already exists, which may suggest that a previous installation attempt was not properly cleaned up or removed.
To resolve these issues, you could try resetting the MySQL user password to meet the policy requirements and then retrying the installation. Alternatively, you could delete any existing databases with the same name as ‘scm’ and then retrying the installation. It may also be helpful to check any logs or documentation provided by Cloudera for further troubleshooting steps.
