Module Description

Common puppet library for Hadoop and its addons. It manages alternatives as used in BigTop-based Hadoop distributions and provides necessary environment variables.

Setup

What hadoop_lib affects

  • Files created (env class):
  • /etc/profile.d/hadoop.sh
  • /etc/profile.d/hadoop.csh
  • Links created (jdbc resource type)
  • Alternatives (postinstall resource type):
  • /etc/<NAME>/conf: it can be switched to the new alternative, so original configuration is kept intact

Usage

Example: alternatives

Package['hive']
->
::hadoop_lib::postinstall { 'hive':
  alternatives => 'cluster',
}

Example: environment

::hadoop_lib::env

Example: MySQL JDBC jar

class { 'mysql::bindings':
  java_enable => true,
}
->
::hadoop_lib::jdbc { '/usr/lib/hive/lib':
  db => 'mysql',
}

Example: array search function

$_myid = array_search($hostnames, $::fqdn)
