I have a weired problem.
as soon as I turn on
pipeline.workers:1
on my piplelines.yml file logstash fails starting up with following error.
[2019-03-26T20:24:12,469][ERROR][org.logstash.Logstash ] java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit
As soon as I put that line in comment and restart logstash it works fine.
But then on another cluster I have this feature enable and setup for each pipeline.
What am I missing?
