Yongjun Zhang commented on IMPALA-6442: --------------------------------------- Thanks for creating this Jira [~zi]. I will be taking a look and just assigned it to me. > Misleading file offset reporting in error messages > -------------------------------------------------- > > Key: IMPALA-6442 > URL: https://issues.apache.org/jira/browse/IMPALA-6442 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 2.11.0 > Reporter: Zoltan Ivanfi > Assignee: Yongjun Zhang > Priority: Minor > Labels: parquet > > {{HdfsParquetScanner::ProcessFooter}} has an error message "File $0 has > invalid file metadata at file offset $1." However, the value reported as > "file offset" is an offset from the _end_ of the file, not from its > _beginning_. This is very misleading, since without explicitly stating that > the offset is from the end, it is usually understood to be counted from the > beginning. > Additionally, although the function name is clearly about a "footer", two > comments explicitly mention processing the "header". This falsely suggests > that metadata is at the beginning of the file, when in reality it is at the > end. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
