Key: HIVE-1442
URL: https://issues.apache.org/jira/browse/HIVE-1442
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Reporter: Namit Jain
Assignee: He Yongqiang
create table T1 (key string, value string) partitioned by(ds string) stored as
sequencefile;
desc extended T1;
insert overwrite table T1 partition (ds='1') select key, value from src;
insert overwrite table T1 partition (ds='2') select key, value from src;
desc extended T1 partition (ds='1');
desc extended T1 partition (ds='2');
alter table T1 set fileformat rcfile;
insert overwrite table T1 partition (ds='1')
select /*+ HOLD_DDLTIME*/ key, value from src;
insert overwrite table T1 partition (ds='2')
select key, value from src;
desc extended T1 partition (ds='1');
desc extended T1 partition (ds='2');
drop table T1;
T1/ds=1 is left as sequencefile and corrupted after the insert as HOLD_DDLTIME
