Description

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 while working on HIVE-23553
