4) Verify you able to connect server MySQL server using the client ( Client Must be installed from which server you connecting), Verify user from ambari-server 192.168.154.111(Client) and 192.168.154.113(server) is MySQL Server IP address
[root@centos ~]# mysql -u hive -h 192.168.154.113 -p
Enter password:
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> select user();
+----------------------+
| user()               |
+----------------------+
| hive@centos.test.com |
+----------------------+
1 row in set (0.01 sec)
mysql> exit;
[root@centos ~]#

5) Above Client not able to connect to MY sql server , we need to grant permission as below.
mysql> grant ALL ON hive.* TO 'hive'@'%' identified by 'hive';
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for hive;
+-----------------------------------------------------------------------------------------------| Grants for hive@%                                                                                   -----------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'hive'@'%' IDENTIFIED BY PASSWORD '*4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC' |
| GRANT ALL PRIVILEGES ON `hive`.* TO 'hive'@'%'                                                      |+-------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

Once more verification from Ambari-server, is Hive username and password is working fine
