这个问题有什么解决办法吗？？？我无法读取Kafkaavro模式消息。我正试图从logstash向kafka和hdfs发送消息。
以下是技术堆栈：
logstash 2.3-当前生产版本
汇合3.0。
插件：a。logstashkafka输出插件b。logstash编解码器avro。
Zookeeper：3.4.6
Kafka：0.10.0.0
日志存储配置文件如下所示：

input {
stdin{}
}

filter {
mutate {
remove_field => ["@timestamp","@version"]
  }
}

output {
  kafka {
topic_id => 'logstash_logs14'

codec => avro  { 
schema_uri => "/opt/logstash/bin/schema.avsc"
    }
  }
}

schema.avsc文件如下所示：

{
    "type":"record",
    "name":"myrecord",
    "fields":[
        {"name":"message","type":"string"},
        {"name":"host","type":"string"}
        ]
}

已运行以下命令：
在自己的终端启动zookeeper
./bin/zookeeper服务器启动。/etc/kafka/zookeeper.properties
2在Kafka自己的终点站出发

./bin/kafka-server-start ./etc/kafka/server.properties

3在自己的终端中启动模式注册表

./bin/schema-registry-start ./etc/schema-registry/schema-registry.properties

4从logstash目录运行以下命令

bin/logstash -f ./bin/logstash.conf

5在运行上述命令后，键入要发送给kafka的日志消息，例如：“hello world”
6.Kafka的主题

./bin/kafka-avro-console-consumer --zookeeper localhost:2181 --topic logstash_logs14 --from-beginning
_While consuming we get the following error:_
