Flink savepoint(checkpoint) recovery dev debug

[qq]

Hi all.

   I want to simulation the shell command which “flink -s savepoint” , this command only can run with shell command, I want to debug it on dev, local development environment, anyone could help me ? Thanks very much. I only can use Savepoint.load to read the savepoint metadata and data. But I want to run the program like "flink -s” on dev phase(use code to run).

Hi

The entrance of restoring savepoint is CheckpointCoordinator#restoreSavepoint [1], hope this could help you.

Hi

You can ref CheckpointMetadataLoadingTest#testLoadAndValidateSavepoint for more information. 

Even more, you can ref the line 136-line145 [1], and init a CompletedCheckpointStorageLocation to make it work.
