FrankChen021 opened a new pull request, #18301:
URL: https://github.com/apache/druid/pull/18301
Fixes #18282
### Description
Improve the auto reset logic as proposed in the above issue:
1. only supervisor is responsible for auto reset. task never triggers the
auto reset flow
2. task always throws `OffsetOutOfRangeException` if this exception is
raised, but will publish ingested message under such case
3. supervisor resets offset to earliest position if it detects offset of a
particular partition is unavailable
4. supervisor starts task more quickly if it needs to reset offsets
5. update the obscure error message like `DataSourceMetadata is not found
while reset` in task report to make it intuitive when supervisor kills a task
because of offset reset
### NOTE
this relies on #18226, which publishes segments when
OffsetOutOfRangeException is raised.
