Timestamp comparisons don't work
--------------------------------
Key: HIVE-2558
URL: https://issues.apache.org/jira/browse/HIVE-2558
Project: Hive
Issue Type: Bug
Reporter: Robert Surówka
I may be missing something, but:
After performing:
create table rrt (r timestamp);
insert into table rrt select '1970-01-01 00:00:01' from src limit 1;
Following queries give undesirable results:
select * from rrt where r in ('1970-01-01 00:00:01');
select * from rrt where r in (0);
select * from rrt where r = 0;
select * from rrt where r = '1970-01-01 00:00:01';
At least for the first two, the reason may be the lack of timestamp in
numericTypes Map from FunctionRegistry.java (591) . Yet whether we really want
to have a linear hierarchy of primitive types in the end, is another question.
