Jorge Esteban Quilcate Otoya commented on KAFKA-9527:
-----------------------------------------------------
> Interesting. Was this part of the KIP design or just a PR-scoped decision?
> Overall, it might be best to align both tools to do the same thing?
I can't find comments about this in the KIP or the thread, so a PR-scoped
decision most probably.
> Well, what would --dry-run print for this case?
Atm prints the end offset.
> The later seems more reasonable to me? Personally, I would still suggest to

Good point. Will create a ticket to follow this up.

> Project: Kafka
> Issue Type: Bug
> Components: streams, tools
> Affects Versions: 2.3.0
> Reporter: jbfletch
> Assignee: jbfletch
> Priority: Minor

> When running the streams application reset tool with --by-duration or
> --to-datetime if any partitions for a given input topic are empty a NPE is
> thrown. I tested this with a topic with 3 partitions, I received a NPE until
> all 3 partitions had at least one message. The behavior was the same for
> both --to-datetime and --by-duration.
> Error below:
