[jira] [Updated] (HIVE-22640) Decimal64ColumnVector:
ClassCastException when partition column type is Decimal
[ https://issues.apache.org/jira/browse/HIVE-22640?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Denys Kuzmenko updated HIVE-22640:
----------------------------------
Description:
{code}
CREATE EXTERNAL TABLE output (id DECIMAL(4,0), foo VARCHAR(10))
PARTITIONED BY (nr_bank *decimal*(4,0))
STORED AS ORC TBLPROPERTIES ('orc.compress'='ZLIB')
insert into output PARTITION (nr_bank=88) values (1,'test');
insert into output PARTITION (nr_bank=8801) values (1,'8801');
select count(*), nr_bank from sdlint.output group by nr_bank;
{code}
The above query fails with:
{code}
Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector cannot be cast to org.apache.hadoop.hive.ql.exec.vector.LongColumnVector
at org.apache.hadoop.hive.ql.exec.vector.expressions.FuncLongToDecimal.evaluate(FuncLongToDecimal.java:58)
{code}
