[SOLVED] Logstash 5.0, downgraded kafka to 4.10. Could not find plugin name kafka

I believe I followed all instructions to downgrade kafka to support my Kafka 0.9.x cluster. Although seems like logstash won't find the downgraded plugin.

bin/logstash-plugin remove logstash-input-kafka
bin/logstash-plugin install --version 4.1.0 logstash-input-kafka
Validating logstash-input-kafka-4.1.0
Installing logstash-input-kafka
Installation successful
  • Version: logstash (5.0.0) and logstash-input-kafka (4.1.0)
  • Operating System: Centos 7.2
  • Config File:
input {
  kafka {
    topic_id => "test_topic"
    group_id => "test_group"
    zk_connect => "host01:2181,host02:2181,host03:2181"
    consumer_threads => 8
  }
}
  • Sample Data:
:reason=>"Couldn't find any input plugin named 'kafka'. Are you sure this is correct? Trying to load the kafka input plugin resulted in this error: Problems loading the requested plugin named kafka of type input."}

I've never removed/installed plugins in the past.

Upgraded to 4.1.1 and problem solvee
