Incorrect indentation and/or mixed format in filebeat.yml causing service to not start

[kobybr]

Filebeat.yml extract:
#================================ Outputs =====================================

#----------------------------- Logstash output --------------------------------
output.logstash:
hosts:
- logstash.********************

enabled: true
certificate_authorities:
  - /var/lib/*********************
certificate: "/var/lib/***************************"
key: "/var/lib/*********************************"

Error message:

service filebeat start

Starting filebeat: Exiting: error loading config file: yaml: line 59: did not find expected '-' indicator

expanding output.logstash to
output:
logstash:

fixes the problem as does removing the two leading spaces on the enabled, certifcate_authorities, certificate, and key.

All fixed in v0.8.4
