Class VectorUDFDatetimeLegacyHybridCalendarTimestamp

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.FuncTimestampToTimestamp

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorUDFDatetimeLegacyHybridCalendarTimestamp

All Implemented Interfaces:

Serializable

public class VectorUDFDatetimeLegacyHybridCalendarTimestamp
extends FuncTimestampToTimestamp

Vectorized version of GenericUDFDatetimeLegacyHybridCalendar (datetime_legacy_hybrid_calendar). Converts a date/timestamp to legacy hybrid Julian-Gregorian calendar assuming that its internal days/milliseconds since epoch is calculated using the proleptic Gregorian calendar. Extends FuncTimestampToTimestamp
