------------------------------
Summary: Support timestamp-micros in AvroSerDe
Key: HIVE-20889
URL: https://issues.apache.org/jira/browse/HIVE-20889
Project: Hive
Issue Type: Improvement
Components: Serializers/Deserializers
Reporter: vinisha
This change only supports timestamp-millis. Avro 1.8.2 also supports
timestamp-micros.
[https://avro.apache.org/docs/1.8.2/spec.html#Timestamp+%28microsecond+precision%29]
timestamp-micros should also be supported in hive AvroSerde because hive
timestamps support nano second level precision.
[https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types#LanguageManualTypes-TimestampstimestampTimestamps]
One possibility is to support avro timestamp-millis and avro timestamp-micros
in serialization. Avro Deserializer can map hive timestamp to timestamp-micros.
