> The {{jobmanager-future}} thread may be blocked at writing metadata to DFS
> caused by a DFS failure, and the {{CheckpointCoordinator Lock}} is hold by
> this thread.
> When the next checkpoint is triggered, the {{Checkpoint Timer}} thread waits
> for the lock to be released. If the previous checkpoint times out, the
> {{Checkpoint Timer}} will not execute the timeout event since it is blocked
> at waiting for the lock. As a result, the previous checkpoint cannot be
> cancelled.
