Apache-Flume

Ansible Role for deploying and configuring Apache Flume

• Deploys Apache Flume
• Configures Apache Flume
• Creates apache-flume service
  • Runs agent only configuration

Requirements

• Running
  • Ansible 2.3+
• Testing
  • Docker/Vagrant
  • Molecule = 1.2.5

Role Variables

• Java vars

  java_heap_xms: 125
  java_heap_xmx: 250
  

• Apache Flume vars

  mirror_url: http://apache.mirrors.ionfish.org/flume
  version: 1.7.0
  

• Linux folder/path install vars

  download_path: /tmp
  installation_path: /usr/local
  owner: root
  group: root
  

• Apache Flume configuration vars
  • Please consult Flume User Guide
  • Currently configuration will allow
    • Agents
      • Service Will Only Be Created For agent
      • mutiple
      • Will need to manually create more services to run these currently
    • source
      • Only allowing one source for each agent currently
    • channel
      • Only allowing one channel for each agent currently
    • sinks
      • mutiple
    • sinkgroup
      • Will add all sinks in agent to sinkgroup
  • Due to high Flume configuration possibilies please read the following
    • Please substitute "." for "_" in your flume configuration for Property Names
      • Values Do Not Need The Substitute
      • Example
        • kafka_consumer_group_id: testflume
      • Result
        • agent.source.kafka.consumer.group.id = testflume
  • Can pass apache_flume_config var to copy configuration over
    • Example
      • apache_flume_config: file/flume-conf.properties
    • Result
      • This will copy the flume-conf.properties from your file directory onto target machine(s)
• Extra variables
  • HDFS native libaries
    • hdfs_libs = true
      • This will pull down HDFS Native Libs and place them in plugin.d/hdfs/native/
