In logstash 6.4.0 on MacOS and oracle jdk 1.8.0_181-b13，use the default setting for kafka output plugin start failed
[logstash.outputs.kafka ] Unable to create Kafka producer from given configuration {:kafka_error_message=>org.apache.kafka.common.config.ConfigException: Invalid value 32768 for configuration receive.buffer.bytes: Expected value to be a 32-bit integer, but it was a java.lang.Long, :cause=>nil}

This should be fixed in the latest version (7.1.3) of the plugin

bin/logstash-plugin update logstash-output-kafka

Thank you

[ericrichter]

this should be documented as a known bug in the release notes and very soon (next monday) be fixed in logstash 6.4.1.

just ran into this issue too with

#rpm -qa | grep logstash
logstash-6.4.0-1.noarch

and doing the /usr/share/logstash/bin/logstash-plugin update logstash-output-kafka

fixed it
