Todd Lipcon commented on HIVE-718:
----------------------------------
OK. How do we come up with a unique name? Just use timestamp?
Does the metastore need to know this name somehow? Or is the change just
localized to that method? (Also, should we rename that method? It's called
copyFiles, but does nothing of the sort)
> Load data inpath into a new partition without overwrite does not move the file

> 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';
