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.

If your issue is resolved then close the thread by accepting the best answer

Happy hadooping

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

 Setup Ambari
# 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)

Highlighted

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

Hi Shelton

 

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

 

Thanks

Can you stop all through ambari and then start all.
Post any errors here 

 

Good job 

Re: Ambari Installation on CentOS 7

Thanks Shelton

 

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 !!
