             Summary: Vectorization: date column throwing java.lang.UnsupportedOperationException for parquet
                 Key: HIVE-21200
                 URL: https://issues.apache.org/jira/browse/HIVE-21200
             Project: Hive
          Issue Type: Bug
          Components: Vectorization
    Affects Versions: 2.3.4
            Reporter: Vipin Vishvkarma


{code:java}
set hive.vectorized.execution.enabled=true; 
set hive.fetch.task.conversion=none; 
create table t1(d date) stored as parquet; 
insert into table t1 values("2019-01-01"); 
select * from t1;
{code}
This query will throw java.lang.UnsupportedOperationException:
{code:java}
Caused by: java.lang.UnsupportedOperationException at org.apache.parquet.column.values.ValuesReader.readLong(ValuesReader.java:131) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedPrimitiveColumnReader.readLongs(VectorizedPrimitiveColumnReader.java:297) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedPrimitiveColumnReader.readBatchHelper(VectorizedPrimitiveColumnReader.java:176) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedPrimitiveColumnReader.readBatch(VectorizedPrimitiveColumnReader.java:154) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedParquetRecordReader.nextBatch(VectorizedParquetRecordReader.java:292) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedParquetRecordReader.next(VectorizedParquetRecordReader.java:238) at org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedParquetRecordReader.next(VectorizedParquetRecordReader.java:64) at org.apache.hadoop.hive.ql.io.HiveContextAwareRecordReader.doNext(HiveContextAwareRecordReader.java:365)
{code}
Above query works fine with Hive 2.1.1 and Hive 3.1.x.
