Todd Lipcon commented on HIVE-718: ---------------------------------- Here's a proposal: How would you guys feel about an addition to the metastore API that is as simple as: string get_unique_id() The metastore would simply keep an autoincrement field to hand these out. We can then use these safely to allocate race-free names to clients. Should be straightforward and a lot more simple than any kind of lock/lease based mechanism. > Load data inpath into a new partition without overwrite does not move the file > ------------------------------------------------------------------------------ > > Key: HIVE-718 > URL: https://issues.apache.org/jira/browse/HIVE-718 > Project: Hadoop Hive > Issue Type: Bug > Affects Versions: 0.4.0 > Reporter: Zheng Shao > Attachments: HIVE-718.1.patch, HIVE-718.2.patch, hive-718.txt > > > 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} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
