Panagiotis Garefalakis reassigned ORC-705:
------------------------------------------
> 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
> Priority: Major
>
> 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
