             Summary: PPD: Date IN single value comparison throws ClassCastException
                 Key: ORC-724
                 URL: https://issues.apache.org/jira/browse/ORC-724
             Project: ORC
          Issue Type: Bug
            Reporter: Panagiotis Garefalakis
            Assignee: Panagiotis Garefalakis


PPD evaluation: after moving to LocalDate and day of epoch instead of java's Date for column statistics in ORC-661 we need to convert Date predicates [to a common type |https://github.com/apache/orc/blob/1d9a289af780c1b35f72269012546d892cf91e14/java/core/src/java/org/apache/orc/impl/RecordReaderImpl.java#L823]make sure they are comparable.

For IN single value PPD evaluation this baseObject [normalization is missing|https://github.com/apache/orc/blob/1d9a289af780c1b35f72269012546d892cf91e14/java/core/src/java/org/apache/orc/impl/RecordReaderImpl.java#L672] leading to ClassCastException:
