Welcome to the MariaDB monitor.  Commands end with ; or \g.

MariaDB [(none)]> use mysql;
MariaDB [mysql]> update user set password=PASSWORD("new-password") where User='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0
MariaDB [mysql]> select * from user;
Empty set (0.00 sec)
If you look user table is still empty :( 
Even i tried to create account but got following error:
MariaDB [mysql]> CREATE USER 'root'@'localhost' IDENTIFIED BY 'new-password';
ERROR 1290 (HY000): The MariaDB server is running with the --skip-grant-tables option so it cannot execute this statement
What i am doing wrong??
By default, MariaDB 5.5 on Amazon Linux 2 doesn't have a root password. If you create a root password for MariaDB and then lock yourself out of your database, you must reset the root password.
Method 1: Use sudo By default, the local root user can log in to MySQL or MariaDB without password, so you can just use sudo mysql instead of mysql , and expect everything to work. Of course, this depends on your sudo to not ask you for a password, or you'll still have to enter one for the root privilege.
FLUSH PRIVILEGES; is needed to load the password table.  Do this after the UPDATE or GRANT.
See the User manual. (MariaDB and MySQL should be identical in this area.)
