-----------------------------------------
Summary: Do not use StatsAccessor when column specified in SELECT
clause
Key: HAWQ-1431
URL: https://issues.apache.org/jira/browse/HAWQ-1431
Project: Apache HAWQ
Issue Type: Bug
Components: PXF
Reporter: Oleksandr Diachenko
Assignee: Ed Espino
StatsAccessor should be used only for queries like COUNT(*) and not
COUNT(column) because we use file-level statistics, which has a total number of
rows, not just number of not-null values.
