Todd Lipcon updated HIVE-718:
-----------------------------

    Affects Version/s: 0.4.0
               Status: Patch Available  (was: Open)

I think we should go ahead with my patch for now and then open another JIRA for fixing the
atomicity issue.

> The bug can be reproduced as following. Note that it only happens for partitioned tables.
The select after the first load returns nothing, while the second returns the data correctly.
> insert.txt in the current local directory contains 3 lines: "a", "b" and "c".
> {code}
> > create table tmp_insert_test (value string) stored as textfile;
> > load data local inpath 'insert.txt' into table tmp_insert_test;
> > select * from tmp_insert_test;
> a
> b
> c
> > create table tmp_insert_test_p ( value string) partitioned by (ds string) stored
as textfile;
> > load data local inpath 'insert.txt' into table tmp_insert_test_p partition (ds =
'2009-08-01');
> > select * from tmp_insert_test_p where ds= '2009-08-01';
> > load data local inpath 'insert.txt' into table tmp_insert_test_p partition (ds =
'2009-08-01');
> > select * from tmp_insert_test_p where ds= '2009-08-01';
> a       2009-08-01
> b       2009-08-01
