[jira] [Commented] (FLINK-36768) Empty Checkpoint Directory created when older checkpoint fails due to timeout and the checkpoint interval is same

---------------------------------

Hi Thomas, thank you for reporting this. From your description, I am not sure which chk-<id> is not properly deleted. Could you provide a more concrete example for your condition. For example, chk-1 trigger -> chk-1 timeout -> at the same time chk-2 trigger, chk-xxx cp directory is not cleaned.

BTW, 1.12.1 is a old flink version (2 years ago). You may use the latest version and check whether the same problem is still existed or not.

> When the checkpoint interval equals the checkpoint timeout, and the failure threshold is reached, the asynchronous checkpoint trigger starts. However, due to an internal restart, the tombstone directory ({{{}chk-<id>{}}}) is not cleared.
