Description

git.commit.id.abbrev=3e8b01d

Dataset :

Every records contains a repeated type with 2000 elements. 
The repeated type contains varchars of length 250 for the first 2000 records and single character strings for the next 2000 records
The above pattern is repeated a few types

The below query fails

ALTER SESSION SET `exec.sort.disable_managed` = false;
alter session set `planner.width.max_per_node` = 1;
alter session set `planner.disable_exchanges` = true;
alter session set `planner.width.max_per_query` = 1;
select count(*) from (select * from (select id, flatten(str_list) str from dfs.`/drill/testdata/resource-manager/flatten-large-small.json`) d order by d.str) d1 where d1.id=0;

Error: RESOURCE ERROR: Unable to allocate sv2 buffer

Fragment 0:0
