[jira] [Created] (IMPALA-8742) ScannerContext::eosr() should
depends on scan_range->bytes_to_read() instead of scan_range->len()
Chen Wang created IMPALA-8742:
---------------------------------
Summary: ScannerContext::eosr() should depends on scan_range->bytes_to_read() instead of scan_range->len()
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
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.
