> 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: 3h 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.
