kafka常见问题及解决方法

启动报错

第一种错误

2017-02-17 17:25:29,224] FATAL Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.KafkaException: Failed to acquire lock on file .lock in /var/log/kafka-logs. A Kafka instance in another process or thread is using this directory.

解决方法：Failed to acquire lock on file .lock in /var/log/kafka-logs.--问题原因是有其他的进程在使用kafka，ps -ef|grep kafka，杀掉使用该目录的进程即可；

第二种错误：对index文件无权限

把文件的权限更改为正确的用户名和用户组即可；

 目录/var/log/kafka-logs/，其中__consumer_offsets-29是偏移量；

第三种生产消费报错:jaas连接有问题

kafka_client_jaas.conf文件配置有问题

16环境上

/opt/dataload/filesource_wangjuan/conf下kafka_client_jaas.conf

 

KafkaClient {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    keyTab="/home/client/keytabs/client.keytab"

        serviceName="kafka"

    principal="client/dcp@DCP.COM";

};

 

生产报错

第一种：生产者向topic发送消息失败：

[2017-03-09 09:16:00,982] [ERROR] [startJob_Worker-10] [DCPKafkaProducer.java line:62] produceR向topicdf02211发送信息出现异常

org.apache.kafka.common.KafkaException: Failed to construct kafka producer

        at org.apache.kafka.clients.producer.KafkaProducer.<init>(KafkaProducer.java:335)

原因是配置文件：kafka_client_jaas.conf中配置有问题，keyTab的路径不对，导致的；

第二种：生产消费报错： Failed to construct kafka producer

报错关键信息：Failed to construct kafka producer

解决方法：配置文件问题：KafkaClient中serviceName应该是kafka，之前配置成了zookeeper；重启后，就好了；

配置文件如下：

KafkaServer {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    useTicketCache=false

    serviceName=kafka

    keyTab="/etc/security/keytabs/kafka.service.keytab"

    principal="kafka/dcp16@DCP.COM";

};

KafkaClient {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    serviceName=kafka

    keyTab="/etc/security/keytabs/kafka.service.keytab"

    principal="kafka/dcp16@DCP.COM";

};

Client {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    useTicketCache=false

    serviceName=zookeeper

    keyTab="/etc/security/keytabs/kafka.service.keytab"

    principal="kafka/dcp16@DCP.COM";

};

衍生问题:

kafka生产消息就会报错：

[2017-05-07 23:17:16,240] ERROR Error when sending message to topic topicin050511 with key: null, value: 0 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)

org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms.

 

把KafkaClient更改为如下的配置，就可以 了：

KafkaClient {

    com.sun.security.auth.module.Krb5LoginModule required

   useTicketCache=true;

};

 

 

 

消费报错

第一种错误：replication factor: 1 larger than available brokers: 0

消费时报错：Error while executing topic command : replication factor: 1 larger than available brokers: 0

解决办法：/confluent-3.0.0/bin  下重启daemon

./kafka-server-stop  -daemon   ../etc/kafka/server.properties

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

   

然后zk重启;sh zkCli.sh -server ai186;

/usr/hdp/2.4.2.0-258/zookeeper/bin/zkCli.sh   --脚本的目录

如果还报错，可以查看配置文件中下面的配置：

zookeeper.connect=dcp18:2181/kafkakerberos；  --是group名称

 

 

第二种错误：TOPIC_AUTHORIZATION_FAILED

./bin/kafka-console-consumer --zookeeper DCP185:2181,DCP186:2181,DCP187:2181/kafka --from-beginning --topic wangjuan_topic1 --new-consumer --consumer.config ./etc/kafka/consumer.properties --bootstrap-server DCP187:9092

[2017-03-02 13:44:38,780] WARN Error while fetching metadata with correlation id 3 : {wangjuan_topic1=TOPIC_AUTHORIZATION_FAILED} (org.apache.kafka.clients.NetworkClient)

 

 

解决方法：配置文件中下面的参数中的User的U必须是大写；

super.users=User:kafka

或者有可能是server.properties中的adver.listen的IP是不对的，有可能是代码中写死的IP；

 

第三种错误的可能的解决方法：

无法消费，则查看kafka的启动日志中的报错信息：日志文件的所属组不对，应该是hadoop；

或者，查看kafka对应的zookeeper的配置后缀，是否已经更改，如果更改了，则topic需要重新生成才行；

 

第三种错误：消费的tomcat报错：

[2017-04-01 06:37:21,823] [INFO] [Thread-5] [AbstractCoordinator.java line:542] Marking the coordinator DCP187:9092 (id: 2147483647 rack: null) dead for group test-consumer-group

更改代码中，tomcat的心跳超时时间如下：

没有改之前的:;

./webapps/web/WEB-INF/classes/com/ai/bdx/dcp/hadoop/service/impl/DCPKafkaConsumer.class;

重启后，日志中显示：

[2017-04-01 10:14:56,167] [INFO] [Thread-5] [AbstractCoordinator.java line:542] Marking the coordinator DCP187:9092 (id: 2147483647 rack: null) dead for group test-consumer-group

创建topic时错误

创建topic时报错：

问题定位：是jaas文件有问题：

解决方法：server.properties文件中的super.user要和jaas文件中的keytab的principle一致；

server.properties:super.users=User:client

kafka_server_jaas.conf文件改为：

 

KafkaServer {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    useTicketCache=false

    serviceName=kafka

    keyTab="/data/data1/confluent-3.0.0/kafka.keytab"

    principal="kafka@DCP.COM";

};

 

KafkaClient {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    keyTab="/home/client/client.keytab"

    principal="client/DCP187@DCP.COM";

};

 

Client {

    com.sun.security.auth.module.Krb5LoginModule required

    useKeyTab=true

    storeKey=true

    useTicketCache=false

    serviceName=zookeeper

    keyTab="/home/client/client.keytab"

    principal="client/DCP187@DCP.COM";

};
