## Problem When a partition becomes a follower but the leader broker is not available in the metadata image, the code only logs at TRACE level, doesn't track the partition as failed, and logs a misleading success message with incorrect count. issue ticket: https://issues.apache.org/jira/browse/KAFKA-19331 ## Solution - Changed log level from TRACE to INFO for better visibility - Added `addFailedPartition()` call to track failed partitions for retry - Fixed log message to use `partitionAndOffsets.size` instead of `partitionsToStartFetching.size` - Added conditional logging to avoid "Started fetchers for 0 partitions" message ## Testing Added unit test `testApplyLocalFollowersDeltaWhenLeaderNotInMetadata` to verify the fix. -- This is an automated message from the Apache Git Service.
