voonhous opened a new pull request, #19916: URL: https://github.com/apache/hudi/pull/19916
### Describe the issue this Pull Request addresses `TestLanceDataSource#testBlobOutOfLine` writes two rows pointing at `[0, 1024)` and `[0, 512)` of one external file. A blob is a distinct entity and two blobs never share bytes (#18098), so `BatchedBlobReader` rejects the pair with `Overlapping blob ranges detected` whenever both rows land in the same Spark task. With the test harness at four shuffle partitions they never did. #19906 moved the harness to two partitions and all six cases failed on Azure ([build 17015, log 98](https://dev.azure.com/apachehudi/a1a51da7-8592-47d4-88dc-fd67bed336bb/_apis/build/builds/17015/logs/98)). Context in #19911. ### Summary and Changelog - `blob_file_2.bin` grows from 1024 to 1536 bytes. Row 4 now references `[1024, 1536)`, disjoint from row 3's `[0, 1024)`. The expected offset for row 4 follows. - No production code change. ### Impact Test only. The Lance out-of-line test no longer depends on which rows share a task. ### Risk Level none ### Documentation Update none ### Contributor's checklist - [x] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [x] Enough context is provided in the sections above - [x] Adequate tests were added if applicable -- This is an automated message from the Apache Git Service.
