Navis created HIVE-3227:
---------------------------
Summary: Implement data loading from user provided string directly
for test
Key: HIVE-3227
URL: https://issues.apache.org/jira/browse/HIVE-3227
Project: Hive
Issue Type: Improvement
Components: Query Processor, Testing Infrastructure
Affects Versions: 0.10.0
Reporter: Navis
Assignee: Navis
Priority: Trivial
{code}
load data instream 'key value\nkey2 value2' into table test;
{code}
This will make test easier and also can reduce test time. For example,
{code}
-- ppr_pushdown.q
create table ppr_test (key string) partitioned by (ds string);
alter table ppr_test add partition (ds = '1234');
insert overwrite table ppr_test partition(ds = '1234') select * from (select
'1234' from src limit 1 union all select 'abcd' from src limit 1) s;
{code}
last query is 4MR job. But can be replaced by
{code}
create table ppr_test (key string) partitioned by (ds string) ROW FORMAT
delimited fields terminated by ' ';
alter table ppr_test add partition (ds = '1234');
load data local instream '1234\nabcd' overwrite into table ppr_test
partition(ds = '1234');
{code}
