Kafka ssl Producer EOFException，而来自Cloud Foundry的Producer.send

Question

在Cloud Foundry中，我能够将消息生成为非SSL链接（“kafkaURL：9092”）。但它不适用于ssl url（“kafkaURL：9093”）。

卡夫卡服务器版本0.10.0.1和客户端版本0.10.0.0。

这里是属性我使用：

props.put(org.apache.kafka.clients.producer.ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, config.getString("obs_q_and_a_db.kafka.metadataBrokerList")) 
props.put(org.apache.kafka.clients.producer.ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, classOf[StringSerializer]) 
props.put(org.apache.kafka.clients.producer.ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, classOf[StringSerializer]) 
props.put(CommonClientConfigs.SECURITY_PROTOCOL_CONFIG, "SSL") 
props.put(SslConfigs.SSL_TRUSTSTORE_LOCATION_CONFIG, "mySslFolder/answersapi.kafka.client.keystore.jks") 
props.put(SslConfigs.SSL_TRUSTSTORE_PASSWORD_CONFIG, "sslTruststorePassword")) 
props.put(SslConfigs.SSL_KEYSTORE_LOCATION_CONFIG, "mySslFolder/answersapi.kafka.client.truststore.jks") 
props.put(SslConfigs.SSL_KEYSTORE_PASSWORD_CONFIG, "sslKeystorePassword") 
props.put(SslConfigs.SSL_KEY_PASSWORD_CONFIG, "sslKeyPassword") 
props.setProperty("metadata.broker.list", "kafkaURL:9093")) 
props.setProperty("serializer.class", serializerClass) 
props.setProperty("message.send.max.retries", maxRetries.toString) 
props.setProperty("request.required.acks", requiredAcks.toString) 
props.setProperty("producer.type", producerType) 
props.setProperty("batch.num.messages", batchNumMessages.toString) 

相同的性质和从卡夫卡使用时相同的证书的文件（信任，密钥库文件）上在外壳采用以下命令卡夫卡服务器工作细壳：

kafka-console-producer --broker-list kafkaURL:9093 --producer.config config --topic myTopicName 

这里是错误：

当我们的客户端代码改为0.10.0.0时，我们的Kafka客户端代码版本：“0.9.0.1”停止工作当我们将客户端代码更改为0.10.0.0时，我们仍然得到相同的EOFileException 当我们替换 弃用的类kafka.producer。{KeyedMessage，Producer，ProducerConfig} 与新的0.10.0类org.apache.kafka.clients.producer。{ProducerRecord，KafkaProducer，ProducerConfig}分别为 顺便说一句，旧的弃用类在指向非SSL url，它们只有在指向Secured Kafka时才会失败URL
