David Morávek commented on FLINK-26916:
---------------------------------------

As long as the operator has access to user credentials (s3), can you simply get 
the latest checkpoint directly from the filesystem?

Having a clean entry in JRS implies that all cluster resources (including HA) 
have been cleaned up (this is not what happens here). Then yes, the id should 
be safe to reuse after cleaning up the entry.
