> 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;
> // this sql sort with partition filed (`dt`) and data filed (`name`), but sort with `name` can not work
> 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)
