Installing Apache Spark via Puppet

Install Java Module into Puppet

/etc/puppetlabs/code/environments/production$ sudo /opt/puppetlabs/bin/puppet module install puppetlabs/java

Install Spark Module to /etc/puppetlabs/code/environments/production/manifests/spark.pp Note that this hard codes server names. Not ideal, but it's a starting point.

$master_hostname='spark-master.bpopp.net'

class{'hadoop':
  realm         => '',
  hdfs_hostname => $master_hostname,
  slaves        => ['spark1.bpopp.net', 'spark2.bpopp.net'],
}

class{'spark':
  master_hostname        => $master_hostname,
  hdfs_hostname          => $master_hostname,
  historyserver_hostname => $master_hostname,
  yarn_enable            => false,
}

node 'spark-master.bpopp.net' {
  include spark::master
  include spark::historyserver
  include hadoop::namenode
  include spark::hdfs
}

node /spark(1|2).bpopp.net/ {
  include spark::worker
  include hadoop::datanode
}

node 'client.bpopp.net' {
  include hadoop::frontend
  include spark::frontend
}

SSH Setup

The master must be able to SSH to the slaves without a password. To do this, you typically use certificates from the master loaded to each slave. From the master:

ssh-keygen -t rsa
ssh-copy-id spark@spark1.lab.bpopp.net
ssh-copy-id spark@spark2.lab.bpopp.net
ssh-copy-id spark@spark3.lab.bpopp.net

Make sure it worked by trying:

ssh spark@localhost

You shouldn't be prompted for a password.

Spark Config
