FlinkSql配置Kerberos环境下的Kafka Source&Sink_flinksql连接kafka, kerberos

1、配置flink-conf.yaml配置文件，将kerberos相关配置放开

security.kerberos.login.use-ticket-cache: true
security.kerberos.login.keytab: /path/to/kerberos/keytab
security.kerberos.login.principal: flink-user
 
# The configuration below defines which JAAS login contexts
 
security.kerberos.login.contexts: Client,KafkaClient

2、kafka flinksql配置

新增这三个配置

  'connector.properties.security.protocol' = 'SASL_PLAINTEXT',
   'connector.properties.sasl.mechanism' = 'GSSAPI',
   'connector.properties.sasl.kerberos.service.name' = 'kafka',

CREATE TABLE person (
    address VARCHAR COMMENT '家庭住址',
     age VARCHAR COMMENT '年龄',
     city VARCHAR COMMENT '所在城市',
     name VARCHAR COMMENT '姓名'
 )
 WITH (
     'connector.type' = 'kafka', 
     'connector.topic' = 'test1',  
     'connector.version' = 'universal',
     'connector.startup-mode' = 'earliest-offset',
     'connector.properties.zookeeper.connect' = 'cdh1:2181,cdh2:2181,cdh3:2181',
     'connector.properties.bootstrap.servers' = 'cdh1:9092,cdh2:9092,cdh3:9092',
     'connector.properties.security.protocol' = 'SASL_PLAINTEXT',
     'connector.properties.sasl.mechanism' = 'GSSAPI',
     'connector.properties.sasl.kerberos.service.name' = 'kafka',
     'update-mode' = 'append',
     'format.type' = 'csv', 
     'format.derive-schema' = 'true'
 );
