FLINKCDC3.0 datastream程序运行测试

1.编写程序本地运行正常

2.程序正常打包

3.提交作业到FLINK集群
./bin/flink run -m hdf1:8081 -c com.org.cdc.FlinkCDCDataStreamTest ./FlinkCdc-test.jar

4.监控作业运行
作业正常运行，cud查看 taskmanager log,可以看到cud变更数据

5.给当前的Flink程序创建Savepoint
bin/flink savepoint 79440d0a1e3f8bf9fbbb0eb5fc04e8e0 hdfs://hdf1:8020/flinkCDC/save

在WebUI中cancelJob
在MySQL的表中添加、修改或者删除数据

从Savepoint重启程序
bin/flink run -s hdfs://hdf1:8020/flinkCDC/save/savepoint-5dadae-02c69ee54885 -c com.org.cdc.FlinkCDCDataStreamTest ./FlinkCdc-test.jar
观察TaskManager日志，会从检查点读取表数据

6.报错 No path for the flink jar passed. Using the location of class org.apache.flink.yarn.YarnClusterDescriptor to locate the jar
该错暂时搁置，无法手动创建保存点
