[jira] [Created] (FLINK-27132) CheckpointResourcesCleanupRunner might discard shared state of the initial checkpoint
Roman Khachatryan created FLINK-27132:
-----------------------------------------
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?
