An error occurred when PrestoDB queried a field with TIMESTAMP type in the
MOR table [Snapshot Mode]
```
org.apache.hadoop.io.LongWritable cannot be cast to
org.apache.hadoop.hive.serde2.io.TimestampWritable
```
**To Reproduce**
Steps to reproduce the behavior:
1.
```
drop table if exists `default`.`spark_0_12_1_test2`;
```
2.
```
CREATE TABLE `default`.`spark_0_12_1_test2` (
`id` INT
,`name` string
,`age` INT
,`sync_time` TIMESTAMP
) USING HUDI
TBLPROPERTIES (
`type` = 'mor'
,`primaryKey` = 'id'
,`preCombineField` = 'sync_time'
,`hoodie.bucket.index.hash.field` = 'id'
,`hoodie.index.type` = 'BLOOM'
,`hoodie.datasource.write.hive_style_partitioning` = 'false'
,`hoodie.compaction.payload.class` =
'org.apache.hudi.common.model.OverwriteWithLatestAvroPayload',
`hoodie.datasource.hive_sync.support_timestamp` = 'true'
)
COMMENT 'test_0.12.1';
```
3.
```
INSERT INTO `default`.`spark_0_12_1_test2`(id, name, age, sync_time) SELECT
2 AS id, 'hudi0121' AS name, 22 AS age, NOW() AS sync_time;
update `default`.`spark_0_12_1_test2` set age = 33, sync_time = now() where
id = 2;
```
4. query with prestodb
```
select * from hudi."default".spark_0_12_1_test2;
```
