Congxian Qiu commented on FLINK-29913:
--------------------------------------
sorry for the late reply.
[~Yanfei Lei] for the priority, IMHO, if the user set \{{
maxConcurrenctCheckpoint > 1 && MAX_RETAINED_CHECKPOINTS > 1 }} , then the
checkpoints may be broken, and can't restore from the checkpoint because of the
{{{}FileNotFoundException{}}}, so I think it deserves to escalate the priority.
[~roman] your proposal seems valid from my perspective, maybe changing the
logic for {{generating the registry key(perhaps using the filename in the
remote filesystem)is enough to solve the problem here?}}
please let me what do you think about this, thanks.
