Yanfei Lei commented on FLINK-29913:
------------------------------------

[~klion26] Since maxConcurrentCheckpoint>1 && MAX_CONCURRENT_CHECKPOINTS>1  are 
less frequently used, I set the priority to Minor.
Under the current checkpoint registration and deletion mechanism, I think this 
bug will take a while to fix, I'd like to fix this problem after discussion.

> Shared state would be discarded by mistake when maxConcurrentCheckpoint>1
