Hi,  
I used Centos 7 with elk stack 6.2.3. After installing x-pack, logstash contantly restarting (systemd). the logs show  
[FATAL][logstash.runner] An unexpected error occurred! {:error=\>#\<ArgumentError: could not coerce automatic into a boolean\>, :backtrace=\>["/usr/share/logstash/logstash-core/lib/logstash/settings.rb:290:in `coerce'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:265:in`set'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:70:in `set_value'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:89:in`block in merge'", "org/jruby/RubyHash.java:1343:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:89:in`merge'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:138:in `validate_all'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:264:in`execute'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/clamp-0.6.5/lib/clamp/command.rb:67:in `run'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:219:in`run'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/clamp-0.6.5/lib/clamp/command.rb:132:in `run'", "/usr/share/logstash/lib/bootstrap/environment.rb:67:in`'"]}  
[2018-04-10T13:15:38,422][ERROR][org.logstash.Logstash] java.lang.IllegalStateException: org.jruby.exceptions.RaiseException: (SystemExit) exit
