In the beginning, we have two concurrent write tasks to write different fields of the same table. 2. The timeline of events is as follows <img width="1277" alt="image" src="https://github.com/user-attachments/assets/43e902a3-9938-464d-8ebf-a306458f1a97";> 3. One write task is done, and then perform a mor snapshot read. 4. And in fs, bucket-0's dir like that: - file: .000000-0000-0000-0000-000000000000_00000000000000.log.1_app_id_0-x-x-x - file: .000000-0000-0000-0000-000000000000_00000000000000.log.1_app_id_1-x-x-x 5. Snapshot reading will scan all log files in bucket-0 with latest committed instant: `ts_2` 7. Scan start: 1. first log in fs is `.000000-0000-0000-0000-000000000000_00000000000000.log.1_app_id_0-x-x-x` 3. scan the blocks in this log, find that block's instant is `ts_4` 4. It's going to think that this log and all the other logs are not needed, so `break` the log scanning. <img width="1052" alt="image" src="https://github.com/user-attachments/assets/91bb5990-1a23-4313-9a02-c034259da375";> 8. `.000000-0000-0000-0000-000000000000_00000000000000.log.1_app_id_1-x-x-x` that needs to be scanned is also skipped. 9. Snapshot reading gets the empty result in bucket-0. **To Reproduce** Same as above **Expected behavior** A clear and concise description of what you expected to happen. **Environment Description** * Hudi version : 0.14 * Spark version : 2.4 * Hive version : x * Hadoop version : x * Storage (HDFS/S3/GCS..) : HDFS * Running on Docker?
