- Default Value: false
- Added In: Hive 3.1.2 with HIVE-21291
Some older Hive implementations (pre-3.1.2) wrote Avro timestamps in a UTC-normalized manner, while from version 3.1 until now .0 until 3.1.2 Hive wrote time zone agnostic timestamps.
Setting this flag to true will treat legacy timestamps as time zone agnostic. Setting it to false will treat legacy timestamps as UTC-normalized.
This flag does not affect timestamps written starting with Hive 3.1.2, which are effectively time zone agnostic (see
for details).Jira server ASF JIRA serverId 5aa69414-a9e9-3523-82ec-879b028fb15b key HIVE-21002
NOTE: This property will influence how HBase files using the AvroSerDe and timestamps in Kafka tables (in the payload/Avro file, this is not about Kafka timestamps) are deserialized – keep in mind that timestamps serialized using the AvroSerDe will be UTC-normalized during serialization. So keep this property false if using HBase or Kafka.
Vectorization
Hive added vectorized query execution in release 0.13.0 (HIVE-4160, HIVE-5283). For more information see the design document Vectorized Query Execution.
