Yun Tang commented on FLINK-13256:
----------------------------------
After digging into the heap dump of jobmanager provided by [~zhuzh], I figured
out the root cause. To be short, this is due to {{currentPeriodicTrigger}} in
{{CheckpointCoordinator}} had been assigned to {{null}} during triggering
checkpoint as there still existed a pending {{checkpoint-387}}. However, the
pending checkpoints would then be aborted due to the region failover and no
active {{currentPeriodicTrigger}} anymore.
> Periodical checkpointing is stopped after failovers

> In this case, we observed that the job initially is triggering periodical
> checkpoints as expected.
> But after 2 region failovers, no checkpoint is triggered any more, even after
> all the tasks are RUNNING again.
> A sample log is attached along with the related topology desc pic.
> This case may not be reproduced every time.
