As your error is as following:

Caused by: java.sql.SQLException: Access denied for user 'ambari1'@'gaian-lap386.com' (using password: YES)

hence you will need to make sure to add the Grant as following for the 'ambari1'@'gaian-lap386.com' user in MySQL DB so that it can connect to mysql from the host where you are running the ambari server.

Example:

# mysql -u root -p
Enter Password: <YOUR_PASSWORD>
mysql> use mysql;

mysql> GRANT ALL PRIVILEGES ON *.* TO 'ambari1'@'gaian-lap386.com' IDENTIFIED BY 'XXXXXXXXXX' WITH GRANT OPTION;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'ambari1'@'%' IDENTIFIED BY 'XXXXXXXXXX' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

In the above command please replace the 'XXXXXXXXXX' with your ambari1 DB user's password.

If you still face the issue then please share the output of the following command

mysql> SELECT user, host FROM user;

.

More details about GRANT and Permissions in Ambari DB can be found in the following link:
