Hi @sunchao / @yigress - I think some of the test failures could be related
to this patch.
http://ci.hive.apache.org/blue/organizations/jenkins/hive-precommit/detail/PR-3492/3/pipeline/439
(which is from the run on this PR)

> Vectorization: wrong results when filter on repeating map key orc table

> Key: HIVE-26447
> URL: https://issues.apache.org/jira/browse/HIVE-26447
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.3, 4.0.0
> Reporter: Yi Zhang
> Assignee: Yi Zhang
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0

> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> Example reproducible case:
>
> set hive.vectorized.execution.enabled=true;
> set hive.fetch.task.conversion=none;
> create temporary table foo (id int, x map<string,int>) stored as orc;
> insert into foo values(1, map('ABC', 9)), (2, map('ABC', 7)), (3, map('ABC',
> 8)), (4, map('ABC', 9));
> select id from foo where x['ABC']=9;
> this only gives 1, when correct result should be 1,4
> For every VectorizedRowBatch, only the first row is checked.
> This seems to be a corner case of ORC table have repeating string type key
> for map field in the MapColumnVector.
