He Yongqiang updated HIVE-718:
------------------------------

    Attachment: HIVE-718.2.patch

the patch that passed tests in my local.
Added the code to undo the copy operation when error occures (this might not help in most
situations, but we should try out best).

> 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
> d       2009-08-01
> {code}
