[GitHub] [kafka] cadonna opened a new pull request #8873: Avoid WARN log message when re-init from checkpoint skipped
cadonna opened a new pull request #8873:
URL: https://github.com/apache/kafka/pull/8873
When a re-initialisation from checkpoint is skipped the following log messages appear in the logs.
```
DEBUG stream-thread [EosTest-a2c3b21b-7af1-4dce-a3e0-6dc10932e5a2-StreamThread-1] task [0_2] Skipping re-initialization of offset from checkpoint for recycled store KSTREAM-AGGREGATE-STATE-STORE-0000000003 (org.apache.kafka.streams.processor.internals.ProcessorStateManager)
DEBUG stream-thread [EosTest-a2c3b21b-7af1-4dce-a3e0-6dc10932e5a2-StreamThread-1] task [0_2] Skipping re-initialization of offset from checkpoint for recycled store KSTREAM-AGGREGATE-STATE-STORE-0000000007
WARN stream-thread [EosTest-a2c3b21b-7af1-4dce-a3e0-6dc10932e5a2-StreamThread-1] task [0_2] Some loaded checkpoint offsets cannot find their corresponding state stores: {EosTest-KSTREAM-AGGREGATE-STATE-STORE-0000000003-changelog-2=1491, EosTest-KSTREAM-AGGREGATE-STATE-STORE-0000000007-changelog-2=1491}
```
The warning appears because the skipped offsets are not removed from the checkpoint. However, there is nothing to warn about, because the offset found there corresponding state stores and they were skipped.
