B is interesting, didn't know it could retry automatically!

I vaguely recall that jobs can queue up in Yarn, so D seems off to me. I think multiple jobs can run concurrently.

I think I read that garbage data can be an issue after a job fails, so C sounds familiar, but I’m not completely confident.

I'm not entirely sure, but I feel like there was a practice question about retries in MapReduce. Could B be right?

I remember something about the Loader job failing if the service is abnormal, so I think A might be correct.

Hmm, the part about generating garbage data if the job fails is concerning. I'll need to double-check that detail.

Option B sounds plausible, but I'm not sure if Mappe tasks can retry automatically. Maybe they need some kind of fail-safe mechanism.

Haha, option D is clearly a joke. No way the Loader can't submit other jobs until the current one is done. That would be a terrible design!

I think option C is the right answer. Garbage data generation after a failed job is a common problem that needs manual cleanup.
