Kalvin2077 opened a new pull request, #3809: URL: https://github.com/apache/celeborn/pull/3809
### What changes were proposed in this pull request? Fix `TierWriter` buffer accounting and reference-count handling when `CompositeByteBuf.addComponent` fails before insertion or during consolidation. Add regression tests and include the shuffle key in write-error logs. ### Why are the changes needed? `addComponent` can fail before or after taking ownership of the buffer. Treating both cases identically can cause incorrect storage counters or buffer reference-count leaks. ### Does this PR resolve a correctness bug? - [x] Yes ### Does this PR introduce _any_ user-facing change? - [ ] Yes ### How was this patch tested? - Added tests for pre-insertion OOM, capacity overflow, and post-insertion consolidation OOM. - Ran `TierWriterSuite`: 11 tests passed. - Ran `./build/mvn spotless:check -pl worker`. -- This is an automated message from the Apache Git Service.
