As promised I tried to recreate your environment on a 1 node cluster running Ubuntu 16.04 in a VM with 12 GB RAM.After the installations find below the high-level steps I performed.
The Cluster is installing without any issues
Generate public and private SSH keys on the Ambari Server host.
root@ubuntu17:~# ssh-keygen
Accepted default values,copy the SSH Public Key (id_rsa.pub) to the root account on your target hosts if multi-node.
.ssh/id_rsa
.ssh/id_rsa.pub
Add the SSH Public Key to the authorized_keys file on your target hosts.
root@ubuntu17:~# cat id_rsa.pub >> authorized_keys root@ubuntu17:~# chmod 700 ~/.ssh root@ubuntu17:~# chmod 600 ~/.ssh/authorized_keys
Set NTPD
root@ubuntu17:~# apt-get install ntp root@ubuntu17:~# update-rc.d ntp defaults
Set the host FQDN in my case the Ambari server vi /etc/hosts ---- IP--FDN--ALIAS
192.168.0.172 ubuntu17.kenya.com ubuntu17
Edit host name
root@ubuntu17:~# vi /etc/hostname ubuntu17.kenya.com
Firewall settings
root@ubuntu17:~# sudo ufw disable The program 'setenforce' is currently not installed.So I installed
The program 'setenforce' is currently not installed.So I installed
root@ubuntu17:~# apt install selinux-utils
Disable SE-Linux
root@ubuntu17:~# setenforce 0
Set UMASK
root@ubuntu17:~# umask 0022 root@ubuntu17:~# echo umask 0022 >> /etc/profile
Download Ambari repo files
root@ubuntu17:~# wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates/2.5.2.0/ambari.list
Grab the key
root@ubuntu17:~# apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD
Update
root@ubuntu17:~# apt-get update
root@ubuntu17:~# apt-cache showpkg ambari-server root@ubuntu17:~# apt-cache showpkg ambari-agent root@ubuntu17:~# apt-cache showpkg ambari-metrics-assembly
Install Java Openjdk comes with JCE
root@ubuntu17:~# sudo apt-get install openjdk-8-jdk
Install Ambari server here I used the root user
root@ubuntu17:~# apt-get install ambari-server root@ubuntu17:~# ambari-server setup
Setup as root user with default postgres databases
root@ubuntu17:~# ambari-server start Ambari Server 'start' completed successfully.
Get the FQDN for the ambari server
root@ubuntu17:~# hostname -f ubuntu17.kenya.com
So my Ambari URL will be http://ubuntu17.kenya.com:8080
See attached screenshot,got an error with THP so had to disable
root@ubuntu17:~/.ssh# cat /sys/kernel/mm/transparent_hugepage/enabled [always] madvise never root@ubuntu17:~/.ssh# echo never > /sys/kernel/mm/transparent_hugepage/enabled root@ubuntu17:~/.ssh# echo never > /sys/kernel/mm/transparent_hugepage/defrag root@ubuntu17:~/.ssh# cat /sys/kernel/mm/transparent_hugepage/enabled always madvise [never]
Setup Mysql database for hive ,oozie etc
root@ubuntu17:~# sudo apt-get update root@ubuntu17:~# sudo apt-get install mysql-server root@ubuntu17:~# sudo mysql_secure_installation root@ubuntu17:~# apt-get install -y libpostgresql-jdbc-java root@ubuntu17:~# apt-get install libmysql-java root@ubuntu17:~# ls /usr/share/java/mysql-connector-java.jar
Check that the mysql connector is present at that location
root@ubuntu17:~# ls /usr/share/java/mysql-connector-java.jar
Create the hive,oozie and ranger databases in Mysql with the correct privileges
created database for hive successfully
created database for oozie successfully
created database for ranger successfully
Run this command
# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
Proceeded with the cluster installation
