---------------------------------
Summary: Casting exception when reading vectorized parquet file
for insert into
Key: HIVE-24947
URL: https://issues.apache.org/jira/browse/HIVE-24947
Project: Hive
Issue Type: Bug
Reporter: Marton Bod
We have two parquet tables (target and source).
Upon running the query:
{code:java}
set hive.vectorized.execution.enabled=true;
insert into target2 partition(tlmtc_fl_gnrtd_yr_nb, tlmtc_fl_gnrtd_mnth_nb)
select * from source;{code}
The following exception is thrown:
{code:java}
Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to [B

The same runs without problems when vectorization is turned off.
Attaching the show create table statements and the sample parquet file so it
can reproduced.
