Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/4693/3/be/src/exec/hdfs-parquet-scanner.cc File be/src/exec/hdfs-parquet-scanner.cc: Line 413: if (row_group.num_rows == 0 || file_metadata_.num_rows == 0) continue; > You could have a corrupt file with num_rows=0 but with some row groups. Wit So I'm right in thinking that the input file is corrupt rather than a valid empty file? I feel like we should call that out somehow, either with a warning or at least a comment here. -- To view, visit http://gerrit.cloudera.org:8080/4693 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I50ac3df6ff24bc5c384ef22e0f804a5132adb62e Gerrit-PatchSet: 3 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Alex Behm <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Internal Jenkins Gerrit-Reviewer: Marcel Kornacker <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-HasComments: Yes
