> ClassCastException during VectorMapJoinCommonOperator initialization

>
> Key: HIVE-19388
> URL: https://issues.apache.org/jira/browse/HIVE-19388
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.1.1, 2.2.0, 3.0.0, 2.3.2, 3.1.0
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
> Attachments: HIVE-19388.01.patch, HIVE-19388.02.patch
>
>
> I see the following exceptions when I a mapjoin operator is being initialized
> on Hive-on-Spark and when vectorization is turned on.
> This happens when the hashTable is empty. The code in
> {{MapJoinTableContainerSerDe#getDefaultEmptyContainer}} method returns a
> HashMapWrapper while the VectorMapJoinOperator expects a
> {{MapJoinBytesTableContainer}} when {{hive.mapjoin.optimized.hashtable}} is
> set to true.
> {noformat}
