I\'ve had little luck searching for this over a couple days.
If my avro schema for data in a hive table is:
{ \"type\" : \"record\", \"name\" : \
select from_unixtime(cast(event_time as bigint) / 1000000) + parse_duration(cast((cast(event_time as bigint) % 1000) as varchar) || 'ms') from TableName limit 10;
