zzzzming95 updated SPARK-40885:
-------------------------------
Description:
When using dynamic partitions to write data and sort partitions and data
fields, Spark will filter the sorting of data fields.
reproduce sql:
{code:java}
CREATE TABLE `sort_table`(
`id` int,
`name` string
)
PARTITIONED BY (
`dt` string)
stored as textfile
LOCATION 'sort_table';CREATE TABLE `test_table`(
`id` int,
`name` string)
PARTITIONED BY (
`dt` string)
stored as textfile
LOCATION
'test_table';//gen test data
insert into test_table partition(dt=20221011) select 10,"15" union all select
1,"10" union all select 5,"50" union all select 20,"2" union all select
30,"14" ;
set spark.hadoop.hive.exec.dynamici.partition=true
set spark.hadoop.hive.exec.dynamic.partition.mode=nonstrict
insert overwrite table sort_table partition(dt) select id,name,dt from
test_table order by name,dt;
{code}
The Sort operator of DAG has only one sort field, but there are actually two in
SQL.(See the attached drawing)
