> Key: IMPALA-8742
> URL: https://issues.apache.org/jira/browse/IMPALA-8742
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.2.0
> Reporter: Chen Wang
> Assignee: Zoltán Borók-Nagy
> Priority: Minor
>
> Normally, scan_range->len() equals to scan_range->bytes_to_read().
> But when SubRanges exists, only bytes_to_read was updated, ScannerContext::GetBuffer would read entire scan_range->len() bytes, and I think it would be a bug.
