Description
Attached vectortest.q
which fails with the below ClassCast Exception
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

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`.
