Ack http://gerrit.cloudera.org:8080/#/c/24579/2/be/src/exec/parquet/parquet-delta-length-byte-array-decoder.cc File be/src/exec/parquet/parquet-delta-length-byte-array-decoder.cc: http://gerrit.cloudera.org:8080/#/c/24579/2/be/src/exec/parquet/parquet-delta-length-byte-array-decoder.cc@73 PS2, Line 73: total_data_bytes > data_len > Is this comparison correct? It's a basic integrity check. total_data_bytes is computed from the decoded lengths. If the page is corrupt (e.g., the delta-packed lengths claim strings totalling more bytes than the entire page), total_data_bytes could exceed data_len. -- To view, visit http://gerrit.cloudera.org:8080/24579 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I9e4395fa30cd7fb2c89ef5a2b16b043d4de60b52 Gerrit-Change-Number: 24579 Gerrit-PatchSet: 3 Gerrit-Owner: Mihaly Szjatinya <[email protected]> Gerrit-Reviewer: Balazs Hevele <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Mihaly Szjatinya <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Comment-Date: Wed, 15 Jul 2026 21:01:20 +0000 Gerrit-HasComments: Yes
