Yes they look fine as they a direct reference to the Hortonworks documentation. Derby databases ain't great for anything apart for development. But its a good pratice to have ONLY one type of database for easy management. And the earlier you start to practice that the better.

That script should have been delivered if you run the MySQL install can you confirm?
Install MySQL for Ambari set auto for Mysql server
# yum install -y mysql-server
# chkconfig mysqld --level 345 on
# yum install -y mysql-connector-java
Then continue with the setup
# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
I am still online
Single Host setup
Ambari UI >> Confirm Hosts >> Success with one warning (The following service should be up and running on 1 host - chronyd)
That's a warning you should be able to continue but run the below on all the hosts in the cluster if it isn't a single node cluster
Use sudo if you don't have root access but permitted in the sudoers
# yum -y install chrony
# systemctl enable chronyd
# systemctl start chronyd
That should works
Installation done with issues though. In HDFS the namenode and snamenode were stopped in first place. Went through a couple of threads, snnode came up. Nnode is still down though
I simply rebooted the server yesterday, went home, this morning it's all gone.
13 critical issues left out of the 53 total reported yesterday. Again your solution works !!
