HortonWorks: Ambari Server Installation

I have been playing around with HortonWorks sandbox and thought it about time I attempt installation on a multi node cluster. Feel free to reach out to me for further support or information. I will be documenting more in the coming weeks.

Add Repo:

wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates/2.6.0.0/ambari.list
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD
sudo apt-get update

Java 8

sudo apt-get install openjdk-8-jdk

Ambari Install

sudo apt-get install ambari-server

Configure Ambari

I recommend installed as non root. In fact do not do any of the defaults for users and passwords. But it is totally up to you. I will document more as I learn more.

sudo ambari-server setup

Ambari Start / Stop / Restart

sudo ambari-server restart
sudo ambari-server start
sudo ambari-server stop

Ambari Server Log Directory

I suggest changing the ambari log directory as well.

sudo vi /etc/ambari-server/conf/log4j.properties

#Look for the property "ambari.log.dir" and change it.
#Don't forget to create the folder you point to and ensure that chown to the user that is running ambari.

Ambari Agent Log Directory

As well change the ambari agent log directory.

sudo vi /etc/ambari-agent/conf/ambari-agent.ini

#Look for "logdir" and change to a directory that exists and has permissions.

Non-Root Install

Running as non-root user you will have to change the run directory because otherwise during a system reboot you may get folders not being able to be created. Because /var/run/ gets deleted on each restart and it get’s rebuilt. Do the following:

sudo mkdir -p /home/##NONROOTUSER##/run/ambari-server
sudo chown ##NONROOTUSER##:root /home/##NONROOTUSER##/run/ambari-server

Then you have to edit the ambari.properties file.

sudo vi /etc/ambari-server/conf/ambari.properties

#Change the following to the folder you created above.
bootstrap.dir
pid.dir
recommendations.dir
