------------------------------
Attachment: HIVE-4149.D9747.1.patch
navis requested code review of "HIVE-4149 [jira] wrong results big outer joins
with array of ints".
Reviewers: JIRA
HIVE-4149 Lazy array returns value of prev row instead of null when called twice
Consider the following query:
create table tinyA(a bigint, b bigint) stored as textfile;
create table tinyB(a bigint, bList array<int>) stored as textfile;
load data local inpath '../data/files/tiny_a' into table tinyA;
load data local inpath '../data/files/tiny_b' into table tinyB;
select * from tinyA;
select * from tinyB;
select tinyB.a, tinyB.bList from tinyB full outer join tinyA on tinyB.a =
tinyA.a;
The results are wrong
