Flink cdc正确打开方式（flink on yarn）

1、Flink on yarn模式下，flink cdc需要先启动yarn-session模式

yarn-session.sh -n 10 -s 2

2、启动之后进行正常测试

CREATE TABLE test1(

id INT

PRIMARY KEY(id) NOT ENFORCED

) WITH (

'connector'='oracle-cdc',

'hostname'='127.0.01',

'port'='1521',

'username'='dwd',

'password'='dwd',

'database-name'='prod',

'table-name' ='test1','schema-name'='dw'

);

select * from test1 limit 10;

3、oracle驱动缺失, on yarn缺失的jar需要拷贝到#FLINK_HOME/lib/

scp ojdbc8-21.5.0.0.jar hdfs@hadoop09:/BigData/run/flink/lib/
