[jira] [Created] (HIVE-16068) BloomFilter expectedEntries not always using NDV when it's available during runtime filtering

Jason Dere created HIVE-16068:
---------------------------------

             Summary: BloomFilter expectedEntries not always using NDV when it's available during runtime filtering
                 Key: HIVE-16068
                 URL: https://issues.apache.org/jira/browse/HIVE-16068
             Project: Hive
          Issue Type: Bug
            Reporter: Jason Dere
            Assignee: 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.
