[~lkqqingcao] would be great to file an issue in English because there are many
maintainers who don't speak other languages.

> sql中使用distribute by ... sort by
> ...时，通过spark/bin/beeline执行的结果错误，使用hive/beeline输出结果正确，具体场景为，先基于posexplode拆分array数据，然后基于拆分的下标进行sort
> by,之后再collect list，结果与原始的array结果不一致，sql如下：
> select id,
> samplingtimesec,
> array_data = new_array_data flag,
> array_data,
> new_array_data
> from (
> select id,
> samplingtimesec,
> array_data,
> concat('[', concat_ws(',', collect_list(cell_voltage)), ']') new_array_data
> from (
> select id, samplingtimesec, array_data, cell_index, cell_voltage
> from (
> select id,
> samplingtimesec,
> array_data,--格式[1,2,3,4,5]
> row_number() over (partition by id,samplingtimesec order by samplingtimesec)
> r --去重
> from table
> WHERE dt = '20221007'
> and samplingtimesec <= 166507920
> ) tmp
> lateral view posexplode(split(replace(replace(array_data, '[', ''), ']', ''),
> ',')) v0 as cell_index, cell_voltage
> where r = 1
> distribute by id
> , samplingtimesec sort by cell_index
> ) tmp
> group by id, samplingtimesec, array_data
> ) tmp
> where array_data != new_array_data;
> 以上sql，对于hive/beeline输出结果为0条；
> 对于spark/beeline输出结果不为0
