``` `[[main]-pipeline-manager] kafka - Unable to create Kafka producer from given configuration {:kafka_error_message=>org.apache.kafka.common.config.ConfigException: Invalid value io.confluent.kafka.serializers.KafkaAvroSerializer for configuration value.serializer: Class io.confluent.kafka.serializers.KafkaAvroSerializer could not be found., :cause=>nil}` 有人用io.confluent.kafka.serializers.kafkaavroserializer使logstash工作吗？
