来自 Cloud Foundry 的 Kafka ssl Producer EOFException while Producer.send

Question

在 Cloud Foundry 中，我能够向非 SSL url ("kafkaURL:9092") 生成消息。但它不适用于 ssl url ("kafkaURL:9093").

Kafka 服务器版本 0.10.0.1 和客户端版本 0.10.0.0。

这是我使用的属性：

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)

从 Kafka shell 使用时在 Kafka 服务器上使用相同的属性和相同的证书文件（信任库、密钥库文件）在 shell 中使用以下命令工作正常：

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

这里是错误：

Answer 1

我们的 Kafka 客户端代码版本：“0.9.0.1”在服务器移动到 0.10.0.1 时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 当我们更换时它得到修复弃用类 kafka.producer.{KeyedMessage, Producer, ProducerConfig} 分别使用新的 0.10.0 类 org.apache.kafka.clients.producer.{ProducerRecord、KafkaProducer、ProducerConfig} 顺便说一句，旧的弃用类在指向非 SSL url 时工作正常，它们仅在指向安全的 Kafka URL

时失败
