[HIVE-17448] ArrayIndexOutOfBoundsException on ORC tables after adding a struct field

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 2.1.1
• Component/s: ORC

Environment

Reproduced on Dataproc 1.1, 1.2 (Hive 2.1).

• Assignee: Aniket Namadeo Mokashi
• Reporter: Nikolay Sokolov
• Created: 04/Sep/17 04:51

Description

When ORC files have been created with older schema, which had smaller set of struct fields, and schema have been changed to one with more struct fields, and there are sibling fields of struct type going after struct itself, ArrayIndexOutOfBoundsException is being thrown. Steps to reproduce:

create external table test_broken_struct(a struct<f1:int, f2:int>, b int) stored as orc;
insert into table test_broken_struct 
    select named_struct("f1", 1, "f2", 2), 3;
drop table test_broken_struct;
create external table test_broken_struct(a struct<f1:int, f2:int, f3:int>, b int) stored as orc;
select * from test_broken_struct;

Same scenario is not causing crash on hive 0.14.
