Prasad Chakka commented on HIVE-718:
------------------------------------

It is possible for users now to add new files to the table/partition directory 
without going through Hive to load files. Hive will pick it up these for the 
future queries. Currently the directory structure is easily inferred and so 
external processes can write and read data independent of Hive. if we start 
having versions then they have to read the correct version from Hive to 
interact with the data. Doesn't this goes against the philosophy of openness? :)

> 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
