Description

The demo like this:

drop table if exists explain_npe_map;
drop table if exists explain_npe_array;
drop table if exists explain_npe_struct;

create table explain_npe_map    ( c1 map<string, string> );
create table explain_npe_array  ( c1 array<string> );
create table explain_npe_struct ( c1 struct<name:string, age:int> );

-- error
set hive.cbo.enable=false;
explain select c1 from explain_npe_map where c1 is null;
explain select c1 from explain_npe_array where c1 is null;
explain select c1 from explain_npe_struct where c1 is null;

-- correct
set hive.cbo.enable=true;
explain select c1 from explain_npe_map where c1 is null;
explain select c1 from explain_npe_array where c1 is null;
explain select c1 from explain_npe_struct where c1 is null;

if the conf 'hive.cbo.enable' set false , NPE will be thrown ; otherwise will not.

Maybe correct in branch of master, but i think it is necessary to initialize the value of StandardConstantStructObjectInspector
