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

             Summary: CheckpointResourcesCleanupRunner might discard shared state of the initial checkpoint
                 Key: FLINK-27132
                 URL: https://issues.apache.org/jira/browse/FLINK-27132
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
    Affects Versions: 1.15.0, 1.16.0
            Reporter: Roman Khachatryan


When considering the following case: # A job starts from a checkpoint in NO_CLAIM mode, with incremental checkpoints enabled
 # It produces some new checkpoints and subsumes the original one (not discarding shared state - before FLINK-24611 or after FLINK-26985)
 # Job terminates abruptly
 # The cleaner is started for that job
 # ZK doesn't have the initial checkpoint, so the store will load only the new checkpoints (created in 2). Shared state is registered
 # The store is shut down - discarding all the checkpoints and also any shared state

 
In 6, if some checkpoint uses the initial state, it will also be discarded
 
[~mapohl] could you please confirm this?
