> Key: HIVE-27479
> URL: https://issues.apache.org/jira/browse/HIVE-27479
> Project: Hive
> Issue Type: Bug
> Components: Query Planning, Statistics
> Reporter: Ryan Johnson
> Assignee: Ryan Johnson
> Priority: Major
> Labels: pull-request-available
>
> For all cases using the BETWEEN key word, the selectivity is outputted as the
> default value because the conditions currently in place make it impossible to
> enter the BETWEEN histogram selectivity code. In addition, NULLs are not
> properly accounted for in the BETWEEN selectivity calculation.
