## Bugbot review **Stream checksum verify misaligns chunks** — `hadoop-hdds/client/src/main/java/org/apache/hadoop/hdds/scm/storage/StreamBlockInputStream.java:638-677` · Severity: high With `checksumVerify` enabled (the default), `verifyChecksumForReadBlock` verifies each chunk overlap without expanding to per-chunk checksum boundaries or indexing into each chunk's stored checksum list. After a prefix of non-checksum-aligned chunks, block-offset alignment can still land inside a chunk mid-checksum-unit, so verification compares freshly computed checksums against the wrong stored entries and stream reads fail with `OzoneChecksumException`. --- Generated-by: Cursor Bugbot -- This is an automated message from the Apache Git Service.
