Product - logstash-5.0.0-beta1 Checked in Gemfile that logstash-input-kafka plugin is available. my logstash-pipeline.conf has below output config. * * * ## output { elasticsearch { hosts =\> ["x.x.x.x:9200","y.y.y.y:9200"] workers =\> 3 } } when I run bin/logstash -f logstash-pipeline.conf --config.test\_and\_exit , I get the following error. _[2016-10-04T13:59:45,652][FATAL][logstash.runner] The given configuration is invalid. Reason: You are using a plugin that doesn't support workers but have set the workers value explicitly! This plugin uses the shared and doesn't need this option_ As per [https://www.elastic.co/guide/en/logstash/master/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-workers](https://www.elastic.co/guide/en/logstash/master/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-workers) , **workers** is a valid setting. Workaround : remove the workers setting from the pipeline config file. Thank you ---
