> In the current implementation, {{Fetcher}} instances usually exit gracefully
> when the shuffle succeeds. When it fails, threads are interrupted, but may
> continue running harmlessly until the JVM shuts down.
> However, to generate consistent checkpoints, these threads should exit
> cleanly to quiesce the state of the shuffle.
