Xiaomin Zhang created HIVE-25548: ------------------------------------ Summary: ClassCastException during VectorMapJoinCommonOperator initialization for some queries Key: HIVE-25548 URL: https://issues.apache.org/jira/browse/HIVE-25548 Project: Hive Issue Type: Bug Affects Versions: 3.0.0, 2.3.0, 2.2.0, 2.1.0 Reporter: Xiaomin Zhang
This issue is very similar to https://issues.apache.org/jira/browse/HIVE-19388. On a Hive release with HIVE-19388 fixed, some queries still failed. set hive.execution.engine=spark; create table if not exists t1(c int, d decimal) stored as orc; insert into t1 values(0, 1); create table if not exists t2(p int, q decimal) partitioned by (d int) stored as ORC; insert into t2 partition(d=10) values(10,2); select c,t.p from t1 join (select * from t2 where t2.d=1) t on t1.d=t.q join (select * from t2)x on x.d=t.d group by c,t.p; Setting hive.mapjoin.optimized.hashtable=false worked, which is the same workaround without HIVE-19388 fix -- This message was sent by Atlassian Jira (v8.3.4#803005)
