This cookbook extends the ambari-chef cookbook to install Hortonworks Data Flow and provision NiFi clusters using Blueprints.
HDF requires Ambari, Java, and Python as prerequisites for installation. These prerequisites can be fulfilled using recipes found in the ambari-chef cookbook or by any other means independently. You can include and customize these prerequisites by modifying the following.
# -- INCLUDE COOKBOOKS --
# ambari-server
include 'ambari-chef::ambari_server_prerequisites'
include 'ambari-chef::ambari_server'
# ambari-agent
include `ambari-chef::ambari_agent_prerequisites`
include 'ambari-chef::ambari_agent'# -- INCLUDE ATTRIBUTES --
# python 2
override['python'] = {
'python2' => {
'packages' => ['python'],
},
}
# java 8
override['java'] = {
'install_from' => 'amazon_source',
'install_version' => 'jdk-8u212-linux-x64',
}By default this cookbook installs HDF version 3.4.1.1. A different version of HDF can be specified for installation by overriding the version attribute.
# hdf
override['hw']['hdf'] = {
'version' => '3.4.1.1',
}Blueprints allow hdf clusters to be programmatically provisioned. A sample hdf_demo blueprint has been included with this cookbook contains core NiFi applications.
You can create your own blueprints and modify the following to push them out with this cookbook
# -- INCLUDE ATTRIBUTES --
# hortonworks hdf cluster
override['hw']['hdf'] = {
'version' => '3.4.1.1',
'cluster' => {
'name' => 'hdf_demo',
'blueprint_name' => 'hdf_demo_3.4.1.1_blueprint',
'blueprint_file' => 'hdf_demo_3.4.1.1_blueprint.json',
'hostmapping_file' => 'hdf_demo_3.4.1.1_hostmapping.json',
},
}To install HDF, include the hdf recipe in your run list. Unless independently handling the perquisites yourself, include the recipes provided by the ambari-chef cookbook as well.
# include prerequisites
include 'ambari-chef::ambari_server_prerequisites'
include 'ambari-chef::ambari_server'
# include hdf
include 'hdf-chef::hdf'
include 'ambari-chef::ambari_cluster'Once installed, log into Ambari at http://127.0.0.1:8080 using admin for both the username and password. The hdf_demo cluster will automatically provision using the included blueprint.
