> {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');
