Hadoop 如何获取配置单元中复杂数据类型列的长度

我有一个配置单元表，其中包含

array

和

map

类型的列，我想筛选array/map列包含多于N个元素的记录，如何操作

DDL:

create table test (id string, v1 array<int>, v2 map<string,string>)

select * from test where length(v1)>10 or length(v2)>10

演示

---

select * from test where size(v1)>10 or size(v2)>10

create table test (id string, v1 array<int>, v2 map<string,string>);
insert into test select 1,array(1,2,3,4,5),map('K1','V1','K2','V2','K3','V3');

select  size(v1),size(v2)
from    test
;
