Camel Kafka java.io.EOFException-NetworkReceive.readFromReadableChannel

我正在尝试使用Kerberos从ActiveMQ骆驼桥向Kafka（Cloudera）生成消息

• ActiveMQv5.15.4
• 骆驼：2.21.1
• 卡夫卡客户端：1.1.0
• 服务器版本：Apache/2.4.6（CentOS）

camel.xml snipet是：

<log message="Started The Producer Route" />
<to uri="kafka://10.100.70.00:9092?topic=MyEvents.s1.v1&amp;brokers=10.100.70.00:9092&amp;requestTimeoutMs=305000&amp;retries=3&amp;keySerializerClass=org.apache.kafka.common.serialization.ByteArraySerializer&amp;saslMechanism=GSSAPI&amp;serializerClass=org.apache.kafka.common.serialization.ByteArraySerializer&amp;securityProtocol=PLAINTEXT&amp;saslKerberosServiceName=kafka"/>

日志级别：调试

Jaas文件：

KafkaClient {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    storeKey=true
    keyTab="./user.keytab"
    useTicketCache=false
    serviceName="kafka"
    principal=" Group/user@DOMAIN.LAN";
};

出口：

KAFKA_OPTS="-Djava.security.auth.login.config=/opt/activemq/conf/Jaas.conf"

当我发送消息时，我在调试级别收到以下日志，但消息未被传递：

在INFO级别，我只在日志中看到：

WARN  | [Producer clientId=producer-1] Bootstrap broker 10.100.70.00:9092 (id: -1 rack: null) disconnected | org.apache.kafka.clients.NetworkClient | kafka-producer-network-thread | producer-1

为什么我会犯这个错误？请帮忙

此错误是由未经授权的用户向卡夫卡发送消息造成的

通过验证keytab文件作为先决条件，可以缓解此类问题：

• 从keytab文件验证服务帐户名：

  klist-k-t

• 通过Active Directory身份验证：

  kinit-k-t

不得有任何错误。

请避免一次问多个不同的问题。请参阅页面以获取澄清此问题的帮助。
