             Summary: Vector PTF ClassCastException with Decimal64
                 Key: HIVE-25117
                 URL: https://issues.apache.org/jira/browse/HIVE-25117

          Issue Type: Bug
            Reporter: Panagiotis Garefalakis


Only reproduces when there is at least 1 buffered batch, so needed 2 rows with 1 row/batch:

{code:java}
set hive.vectorized.testing.reducer.batch.size=1;
{code}

{code:java}
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
