>                 Key: HIVE-16068
>                 URL: https://issues.apache.org/jira/browse/HIVE-16068
>             Project: Hive
>          Issue Type: Bug
>            Reporter: Jason Dere

> The current logic only uses NDV if it's the only ColumnStat available, but it looks like
there can sometimes be other ColStats in the semijoin Select operator.
