Fly365 updated FLINK-35036:
---------------------------
Description:
With the Flink CDC job, I want oracle data to doris, in the snapshot，canel the
Flink CDC Job with savepoint,the job cancel failed.
Using Flink CDC, synchronize the data tables of Oracle 19C to Doris. During the
initialization snapshot phase, some data was synchronized but has not yet
reached the incremental phase. At this time, cancel the CDC task and save Flink
Savepoint, but the task cancellation fails; After the task enters the
incremental phase, it is possible to cancel the task and save the savepoint.
Why did the savepoint fail during the stock data synchronization phase?
使用Flink CDC,将Oracle
19C的数据表同步到Doris中，在初始化快照阶段，同步了一部分数据但还没有到增量阶段，此时取消CDC任务并保存Flink
Savepoint,取消任务失败；而在任务进入增量阶段后，取消任务并保存savepoint是可以的，请问存量数据同步阶段，为何savepoint失败？
