------------------------------------------
Summary: Predicate evaluation should take into account writer
calendar
Key: ORC-705
URL: https://issues.apache.org/jira/browse/ORC-705
Project: ORC
Issue Type: Bug
Components: Reader
Affects Versions: 1.6.6, 1.7.0
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
RecordReaderImp should pass down the writer calendar info
(writerUsedProlepticGregorian) when evaluating predicates to make sure column
stats are properly deserialized (affects TimestampStatistics).
Currently, the reader assumes that a writer always uses a ProlepticGregorian
calendar for timestamp stats which is not always the case.
Discovered this issue when working on HIVE-23553
