Hi yichao,

There is a checkpointing IT test here[1]. You can run it locally and set breakpoints to debug.

Furthermore, you can search other checkpointing test cases in Flink git. 

Best, Hequn

Hi Hequn,

Thank you for your help.  My real purpose is to debug the following code in IntelliJ IDEA . 

I want to start the flink job in IDEA, the 54th line of code can get the states in the previously stored savepoint or checkpoint, at line 56 the  context.isRestored() can return true. Do you have any idea to do this in IDEA?

Hi yichao,

A similar question[1] was asked a few days ago. I think it would be helpful to answer this question. 

Best, Hequn

Hi，
I want to debug the flink job in the local IntelliJ IDEA to restore the initializeState from the snapshot of a previous execution . How do I set the parameters to allow the program read the checkpoint or savepoint data from hdfs to restore the state of the program?
