AWS EC2 MySQL Client Installation - mysql

Question

I am installing MySQL client in my EC2 instance via Cloudformation using the below command in userdata:
- yum install -y https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
- yum install -y mysql-community-client.x86_64
But after logging-in to the EC2, I found that I cannot execute certain commands like
mysqldump
mysql
I checked in /usr/bin and found that mysql, mysqldump, mysqlcheck and other mysql related commands are not there.
At last I checked the system log and cloud-init log of the EC2 server and found below log:
