[jira] [Updated] (HIVE-27632) ClassCast Exception in Vectorization converting decimal64 to decimal
[ https://issues.apache.org/jira/browse/HIVE-27632?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Riju Trivedi updated HIVE-27632:
--------------------------------
Attachment: vectortest.q
Component/s: Vectorization
Description:
Attached [^vectortest.q] which fails with the below ClassCast Exception
{code:java}
Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.ql.exec.vector.Decimal64ColumnVector cannot be cast to org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector
at org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterDecimalColEqualDecimalScalar.evaluate(FilterDecimalColEqualDecimalScalar.java:64)
at org.apache.hadoop.hive.ql.exec.vector.VectorFilterOperator.process(VectorFilterOperator.java:125)
at org.apache.hadoop.hive.ql.exec.Operator.vectorForward(Operator.java:919)
at org.apache.hadoop.hive.ql.exec.TableScanOperator.process(TableScanOperator.java:171)

at org.apache.hadoop.hive.ql.exec.vector.VectorMapOperator.process(VectorMapOperator.java:878)
{code}
This seems related to HIVE-26208 , which avoids Decimal64 to Decimal conversion for the vector expressions that explicitly handle decimal64 types. However, in this scenario exception comes from `FilterDecimalColEqualDecimalScalar`.
Summary: ClassCast Exception in Vectorization converting decimal64 to decimal (was: ClassCast Exception in FilterDecimalColEqualDecimalScalar converting decimal64 to decimal)
