Panagiotis Garefalakis created ORC-724:
------------------------------------------
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:
{code:java}
java.lang.ClassCastException: java.time.LocalDate cannot be cast to
java.util.Date at java.util.Date.compareTo(Date.java:131) at
