----------------------------------------------
Summary: java.lang.ClassCastException:
org.apache.hadoop.hive.serde2.lazy.LazyStruct cannot be cast to
org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch
Key: HIVE-21064
URL: https://issues.apache.org/jira/browse/HIVE-21064
Project: Hive
Issue Type: Bug
Reporter: Jesus Camacho Rodriguez
The error is present in one of the test files (parallel_orderby.q) and it was
discovered while working on HIVE-16957. To reproduce:
{code}
set hive.mapred.mode=nonstrict;
set hive.stats.column.autogather=false;
create table src5_n2 (key string, value string);
load data local inpath '../../data/files/kv5.txt' into table src5_n2;
load data local inpath '../../data/files/kv5.txt' into table src5_n2;
set mapred.reduce.tasks = 4;
set hive.optimize.sampling.orderby=true;
set hive.optimize.sampling.orderby.percent=0.66f;
create table total_ordered as select * from src5_n2 order by key, value;
{code}
The create table statement throws the following exception:
{code}
java.lang.ClassCastException: org.apache.hadoop.hive.serde2.lazy.LazyStruct
cannot be cast to org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch
{code}
The exception is printed in the q file. This was introduced when HIVE-18910 was
checked in, I am not sure whether it is a known issue. Cc [~djaiswal] [~jdere]
