Alexander Pivovarov commented on HIVE-10488: -------------------------------------------- Got it! Thank you. BTW, I remember it was one issue with date to timestamp conversion for negative unix time HIVE-10178. But it is fixed already and has nothing to do with Orc. {code} select cast(cast('1966-01-01 00:00:01' as timestamp) as date); 1966-02-02 {code} > cast DATE as TIMESTAMP returns incorrect values > ----------------------------------------------- > > Key: HIVE-10488 > URL: https://issues.apache.org/jira/browse/HIVE-10488 > Project: Hive > Issue Type: Bug > Components: SQL > Affects Versions: 0.13.1 > Reporter: N Campbell > Assignee: Chaoyu Tang > > same data in textfile works > same data loaded into an ORC table does not > connection property of tez/mr makes no difference. > select rnum, cdt, cast (cdt as timestamp) from tdt > 0 <null> <null> > 1 1996-01-01 1969-12-31 19:00:09.496 > 2 2000-01-01 1969-12-31 19:00:10.957 > 3 2000-12-31 1969-12-31 19:00:11.322 > vs > 0 <null> <null> > 1 1996-01-01 1996-01-01 00:00:00.0 > 2 2000-01-01 2000-01-01 00:00:00.0 > 3 2000-12-31 2000-12-31 00:00:00.0 > create table if not exists TDT ( RNUM int , CDT date ) > STORED AS orc ; > insert overwrite table TDT select * from text.TDT; > 0|\N > 1|1996-01-01 > 2|2000-01-01 > 3|2000-12-31 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
