Lu Niu updated FLINK-22326:
---------------------------
Description:
Job contains Iterate Operator will always fail on checkpoint.
How to reproduce:
[https://gist.github.com/qqibrow/f297babadb0bb662ee398b9088870785]
this is based on
[https://github.com/apache/flink/blob/master/flink-examples/flink-examples-streaming/src/main/java/org/apache/flink/streaming/examples/iteration/IterateExample.java,]
but a few line difference:
1. Make maxWaitTime large enough when create IterativeStream
2. No output back to Itertive Source
Result:
The same code is able to checkpoint in 1.9.1

but always fail on checkpoint in 1.11
