Renukaprasad C commented on HIVE-23927: --------------------------------------- Thanks [~jcamachorodriguez] & [~pgaref]. We will do the similar implementation as other integer datatype conversion (As suggested by [~pgaref] -Maybe we should make this configurable as well – as we do in longToTimestamp method) in *PrimitiveObjectInspectorUtils.getTimestamp(Object, PrimitiveObjectInspector, boolean).* > Cast to Timestamp generates different output for Integer & Float values > ------------------------------------------------------------------------ > > Key: HIVE-23927 > URL: https://issues.apache.org/jira/browse/HIVE-23927 > Project: Hive > Issue Type: Bug > Reporter: Renukaprasad C > Priority: Major > > Double consider the input value as SECOND and converts into Millis internally. > Whereas, Integer value will be considered as Millis and produce different > output. > org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorUtils.getTimestamp(Object, > PrimitiveObjectInspector, boolean) - Handles Integral & Decimal values > differently.
